'robo devil' or 'devil robot' might have worked better...i've never heard anyone use the word 'robo' as a noun before.

Very freaky, but seems a little too "Hot Topic" for me.

how do you pronounce "<"?

devil robo is the character name, and the "<" is the typographic element.

then the character has a grammatically wrong name. and does that mean 'devil robo' is 'less than' everything else? you said, it, not me.

maybe it's like, Spanish or something, like "chica loca" and robo really IS the adjective. I dunno. make it in tiny sizes and then stuff it in a transformer package.

it looks nice, but if it's a character you've developed yet haven't marketed, i don't see the point of it on a shirt. marketing stuff on this site doesn't seem like the most effective use of your time. if you insist on keeping the text, make toys or lunchboxes or whatever until people readily recognize the character, then it'll be shirt worthy. otherwise, maybe dump the text and replace it with some other element. it is well done, btw.

Is this Edward Sissorhand's pet?

that reminds me of that bat digimon. cool design though.

personally i dont like the idea, or the final product, but it IS very well executed, nicely done, very clean, and i HIGHLY commend you for using vectors. i cant deny that. but i still have my opinion, and i wouldnt buy it.

some tips though:

1) ditch red-black-white color scheme. it makes it immediately goth/punk/hot-topic/dark-type.
2) consider placement of elements inside your design. study other submissions, make note of how they used their typography.
3) consider placement of the actual full design on the shirt. you might want to consider running the typography down the side of the shirt, or across the shoulderblade-into the top of the sleeve/shoulder... diagonal... experiment with it.
