As many people have said already the best thing about this site is the incredible amount of help and advice that people are willing to give to you for free. I remember when I first stumbled upon renderosity and saw the quality of the work in the galleries and thought to myself 'I wonder how you do THAT?' LOL! But never be afraid to ask a question, no matter how silly it sounds! We've all asked them, me probably more than most LOL! Out of interest what's the commic about? Are you able to give a brief synopsis? Good luck and happy rendering!
