Ugandan Knuckles

Commission piece from fiverr. The request was to paint the Ugandan Knuckles with one side being his skeleton and he must have nipples. This is the most unique commission piece I have done so far. Critiques and comments are welcome! :)
Thank you Toko Suzuki and Marc Brunet for sharing your brushes.
