I know that geometrically "S" is ok in the middle but visually it looks broken. Correct that. Its weight also looks heavier as other letters'.

I like the second one more, but it reminds me of the YOSHO (90560) because of the "Y" style.

Since it's about seeing. There's a nice "eyes" pattern with "e"s at the end. Add some eyebrows or eyelashes maybe. Try and play.

But I like the cleanness of it. Very clean very nice. Less is more. Just make it memorable somehow.

Thanks for that Litera. Working on the 's' at the minute.
I thaink I'll refrain from the eyebrows and eyelashes though.

to me, the treatment of the "y" is better on the first example. i don't know why, but that one i read as "you see", while the second registers with me closer to "yowsa."

robert is right about the "s."

I like the top 'y' best.

Definitely the top, the bottom looks like some odd variation of “house.”

I prefer the 'y' in number 2. The tail in number 1 makes it look more like a 'u', which may be good in that that is the sound made by the word (yoo), but it looks odd. I think you right to refrain from the eyes and eyelashes.
Any thoughts on colours or a supporting image at this point?

I would work on reducing the weight in the curved parts of the letters – there is a horizontal weightiness at the top and bottom of most characters, and try a more geometric s based on the shape of the e with a horizontal crossbar. A little bit of overshoot on the curved characters could help the baseline which is dragged down by the y, or you could exaggerate it to make a small feature of it. The transition from vertical to curved in the inside of the y,o,u is a bit abrupt.

Nice one. Very useful comments. Will post a revised version shortly. Thanks
