First, there is no need to apologise for your English.
I don’t think unicase is the way to go to hint at prestige I would look at more “traditional” serif faces. Also I wonder if you could make the circle round the frequency into a crystal so that the frequency on its own could be used if required. I found your first sketch more in keeping with the demographic although an alternative to the existing typeface might be more elegant Bliss leaps to mind but there are many alternatives, and look at upper and lower case. The fm ligature works very well in the first sketch version.
For the second I would also look at upper and lower case, this might sort out the spacing issues of the LYW, instead of the infinity moebius loop you could look at an oo ligature in the vein of Mrs Eaves. The point for the frequency should move up to align with the centre of the 3. The illustration is charming, but maybe it should move down a bit and the weight of the bubble chair stroke could be a bit lighter.

fedezz, these days who cares about am or fm. Most radio stations have a link to on-line streaming. My point being, in emphsis bury the fm all together make it tiny.

The 107.9 cristal are static not dynamic. Make the 107.9 shape move or give it dimention. Maybe its exploding with sound, like how you would feel if you were stuck in front of a sub-woofer. That age group is a go-go group (think ipod, or ishuffle) media goes with them (cell phones with internet access). The type isn’t the problem.

101.3 Hollywood is just boring. Try doing something with the traditional Hollywood hills lettering. Also explore something classy and classic like a Tragian movie title look. The mark on the first version leaves me cold, it means nothing to anyone.

Now you’ve made a good start, keep going, and post some more. Think less about design and more about your target audience and you will have winners.

timd: the problem with u/l cases is that I only have one ascendent in the whole word (l), and gives me a weird shape. In hollywood it gets even worse. What do you mean with “make the circle into a crystal”? The shape? Volume, 3d or some effect? Where can I get information about Bliss? I looked in myfonts.com and found no info there...
Regarding the second logo, your comments were quite useful, I´ll try to update that as soon as possible.

dgweaver53m: actually, the client made emphasis in the importance of the station name being “cristal fm” (forbidding cristal, fm cristal or any other combination). I have no saying in that matter. I´m keeping in mind the target, the problem is that reality is a little bit different here in Argentina than in Europe or the states :) The actual logo has the word “Cristal” set in an Illustrator-condensed Bodoni, and the client wants to mantain at least some relation with it. Besides, being a contest, I have to make peace between what I like and think about design and the client´s willings :)
Actually I thought about the hills thing, but I think it´s kinda cheesy, and it will not relate to the music or the concept. Also, it´s supossed to comunicate calm, relax, chill.

Thanks for the feedback, I will post some updates soon.

I am not a fan of all uppercase setting, but you have ascenders (of a sort) with the C, i, and t. HOLLYWOOD set in uppercase gives you all kinds of problems with negative space around the centre of the word which, with application, you could reduce. I didn’t want to dictate the shape of the final logo (and I’m not certain it will work) so I left the suggestion of shape hanging but you could start with a simple lozenge and introduce 3d, just to see if you think it will work.
While you are looking at Bliss take a look at Aspect.
With re-reading my comments on the Hollywood illustration are not clear I meant the figure should move down to settle it into the chair.

fedezz, my thought on the Hollywood hills lettering was about demographics (its dated), wouldn’t be associated with anything but middle aged listeners. I didn’t realize your dealing with a South American client. Try researching the lettering of the period of the music they play, maybe something will grab you.

Since this is a competition, your competitors might try some more edgy designs and catch lightning in a bottle. Don’t paint yourself into a corner or you will loose. My problem with your logos is they aren’t promotional enough yet. They don’t screem enough, and radio stations scream!

Dan,
I would suggest that using fonts from the 80s and 90s would produce a logo not quite dated enough to be retro and in fact might appear in need of an update. As for the Hollywood Hills lettering when does that date from?
