well here's my design of Ben in my Ben 10 doujinshi. Not much difference between him and the original. Hair is longer because this takes place 2 years after the cartoon (to be specific, the 'Secret of the Omnitrix' Movie) I designed a jacket for him to wear vut didn't put it in the picture because he doesn't wear it until later in the comic. Will clean up pencils in the colored version.
P.S. this goes without saying, but I so did not create Ben 10. And i dont own it either
