Hello, I'm Hisham. The style I take in illustrations differs according to the client's requirement. I see that you're after some of the traditional biker and related styles, which I'd like to assist you in creating.
Recently I did a character illustration set for PathfinderRPG, more of a fantasy related art, not the style you're after; But I believe seeing few of them may be a good idea to see whether I'm 'bad ass' enough :)
and oh! I'm a graphic designer and illustrator, mostly doing my artworks in Adobe illustrator as I'm a fan of vector illustrations.
I'd like to show you some of my illustrations now itself if you're interested or I can E-mail a few as you have requested. I pay much attention to detail and I like my designs to be complete in terms of quality and originality.
I would like to hear more about your ideas for the apparel and about the timeframe.
Looking forward to hear from you,
Best Regards
