Oh my, that belly's big even by pregnant standards. Surprised she doesn't have an outward bellybutton, as it makes her look more fat than pregnant (maybe she's becoming both?). I still love this picture though. It's nice to see she's enjoying her transformation.
I'd be up for a commission myself if I wasn't trying to save for some tools for my own artistic endeavors.
Normally I wouldn't draw lactation/pregnancy but it was for the commissioner. I haven't drawn like this stuff before actually (this exaggerated anyways) and it turned out better than expected I'm glad you like it!
