Looks like you're doing pretty good. You know, creating a successful character or characters doesn't just depend on technical expertise. It also has a lot to do with embuing it/them with that special something that makes it yours and communicates to the viewer (one at a time I say - no such thing as a large audience with print work) what you are intending to give to it/them. You can enhance this area with reference, seeing what others (more than one, else it borders on plagiarism instead of research) but when you get that GOOD FEELING OF SATISFACTION of seeing your creation "come to life" -- and you'll know when -- you're probably pretty much on the right track. Having said that, some sources of reference might be some old Tom of Finland work for motorcycle, cop and leather boys -- updated of course -- and maybe a bit esoteric here -- Trashman, who rode a WICKED bike, by the great Spain Rodriguez or maybe his colleague and fellow great, S. Clay Wilson, for my money the best inker to come out of the underground, though he is and was a masterful creator of parody and pencil work. And, you can't go wrong with just research for its own sake, for my money one of the top pleasure perks of doing any project, especially comics. Then again, don't sell yourself short! Looks to me like you're pretty much on the right track. You will make some mistakes but, hey, that's life! Larry F
