Nice work
I watched the screen recording, was nice to see how it all came together. The pin up itself amuses me slightly since it looks a lot of one of someone who I try to avoid at all costs now ^_^
Anyways on an artistic level it's good work, maybe in the dark green of the top it could have benefited from a few more slightly darker green shadows i.e near to where the arm would be blocking the light more, to give it more shape/depth/definition etc
Overall good work. :)
