Figured I'd start a thread here, too.
For those of you who don't know me, I'm Jim, aka OrcaDesignStudios. For a long time, I'd been focused entirely on 3D art, but I'm back now to doing mostly 2D stuff. Been drawing pretty much since I was born and I'm always looking for new techniques to try and new ways to improve.
A lot of my recent sketches have been done using Prismacolor markers. I recently picked up a couple sets and I use the sketches to get accustomed to their quirks.
My weapons of choice are 3H and 2H pencils for rough work, H or HB for finished pencils. I used to do all my roughs in non-photo blue, but I found that the Prismacolour markers didn't play well with npb pencil, so now the only time I go npb is if I'm scanning to colour digitally.
I'll start off my sketch thread with the oldest sketch I have: Darth Vader, from way back when I was 5 years old!
