Used the back of a comic for reference.  I'd like to change teeth, but I hate spending too much time on one piece when pixeling.  I was thinking about redoing the whole piece from scratch but without pixel by pixel techniques, rather all photoshop painting techniques available,. in photoshop reducing to same number colors, then cleaning it up post.  The goal would be to comparing production times, and results.  The second approach wouldn't be purist pixel art, but  what's the consensus? 

I could have stripped out 4 more colors to make it a nice round power of 2 but no programmer is waiting for this.
