#34 and #35 don't really work either. We don't want a superhero icon in there. More of just a geeky character, but in a more fun-loving kind of way. Your first character was too much like an anime one (#11), but this one is too much like Superman. Just go for a fun, cartoony, simplistic person.
Also, we like the color scheme from #10 , so please try to incorporate that into the logo.
