Hey,
I am trying to make some custom letters for my own identity but I am not satisfied enough.
Could you give me some help? Or maybe this is just not good?

I think the lettering style looks cool - I guess it just depends on what you want your logo to say about you. I see "modern", "friendly", "slightly techno", "systematic yet playful".
I like the stacked version. I also enjoy the n-i pair and how your "a" is the reverse of your "e". I would tweak the kerning a bit here and there: I think you need to tighten up d-a and s-m

The /l/s look too close to the other letters. I see the appeal of the tight interlocking in the stacked version, but my eye still gets hung up on the fact that, serifs aside, the EL and YL spacing is far far tighter than any other letters. Consequently it looks a little smashed in on the right side.
