This was one of two commissions I took back in early May. I assumed my work would dry up as the project is coming to a close, however, I am still working full time on the final stage, so this, and my next commission took a little longer than planned.
That said, it was pretty painless to work on and the end phase was easy, though when it came to rendering Galiena I did get stuck. I think the main thing to remember when it comes to rendering figures is to just be messy and not to worry about things looking right on the first pass. Most paintings look horrible to a certain point anyway and rendering line-drawn babes is just the same. There are no magic tricks to keep things clean throughout the whole process.
Overall I guestimate this took me about 25 hours or thereabouts. Enjoy! :)
