Horace Digital Painting

I may officially have a problem.  I love drawing Horace Gentry.  He's just so fun to draw, and he's a character I have some attachment to, since I play in a regular D&D session as him.  This piece in particular I busted out right before bed, thinking I was going to do a quick sketch.

Well, I went a little further, and did this piece in about 2 hours with Photoshop and my Wacom tablet.  When I've been running on the treadmill I'll do some painting in my head sometimes.  Imagine new ways to show hair highlights, blend skin tones, etc.  So, I was dying to do another Horace piece in a new style.  It's obviously way more detailed than I usually do.  I was pleasantly surprised at how it turned out.

One day I'd love to write up my digital painting process.  Of course, I know I'm not nearly as good as most people that I'm drawing my inspiration from, but I'd love to know how my process stacks up to other profressional digital painters.
