goofydoug-- i like.
Reflex5.5-- i'm not a rendering pro but i'll share some things i've learned: use a harder brush w/ lower opacity for some parts so it's not so soft/fuzzy. and use multiple layers (see what happens when you set some to 'multiply') to build up value and to more easily render certain areas (highlights, hard reflections, etc)
'93 Passat GLX-- thanks, i do what i can but i'm not at the level i want to be. i used photoshop.
TickTack-- black_sheep is right, learn by hand first; it's all practice and observation. although i wouldn't stay away from pencil completely, it can be a good tool if you use it right (but i'd recommend prismacolor instead of a regular #2)
username-- andy how's everything been in detroit? nice old-school style, was that from back in the day at school?
yurikaze-- the world-famous yuri. that's all that needs to be said. somehow everyone either knows you or knows someone who knows you. anyway, we need to get down to business one of these sketchfests instead of just playing mario kart or watching movies, are we sketchfesting in candyland this sunday?
