Somewhere between steps 3 and 4

I'm not sure I have my tones (step 3) completely worked out, but I was feeling a tad stuck, so I thought experimenting with color studies (step 4) might help nudge me forward.

I also went back and refined the lines of my sketch after looking at Will Terry's PSD file some more. I realized his sketch was much cleaner than mine and if I want to get a result similar to his, I better make sure my piece is working from the ground up.
