I think this is GREAT!!! It totally captures that retro 80's arcade feel that I was looking for! I love the space helmet with headphones, I love the "Galaga" word with the green outlined in that cool orange/yellow... Try some different things with the word "radio" please. Don't get me wrong, I like how it is... but I wanna see what else you can do with that part of it. The color is GREAT. I like the stars... I like the helmet. Not sure about the sideways "radio" - but it's growing on me...
I normally wouldn't trouble a designer over such a small change, but i'm 99.9% sure i'm going with your #19 - The star that sits in the hole where the "L" is... Can i see that star a little more prominent and white in color? I understand if you dont have the time.
