Helloski,
I've been really interested in finding out how other people paint metal skin/figures digitally. Lately I've been practicing and getting better. I'd like to see some metallic figures from you guys. Below are some of the first stages I used when I began.
Programs that can mimic tradtional painting would be the best things to use, in my opinion. And if you are relatively new to digital painting, it would probably be best to keep everything in seperate layers (assuming you are using something like Photoshop), duplicate and hide+lock layers that you feel like you might ruin so that you can easily jump back if all goes to hell. Sometimes, if you are smudging a line along or whatever, you might rack up more actions than your history records.
Anyways, these were created in Macromedia Flash 8 (clean outline) and Photoshop 7.0 (everything else but sketch). Good luck! ^_^
