This probably would have went faster if I flatted it because it's such a simple image, but I was lazy. Plus I've been in a flow just sketching in my sketchbook, so it was a little hard breaking that up. I actually started this because I saw it and wanted it as my desktop, but didn't want just the b&w sketch.
So, sketch cleanup + paints (not flatted), finished in a little under 3 hours. Considering I haven't colored anything (besides that recent commission) in a while, not too bad I think.
