4k reference sheet - Derpy

This was a commission for someone. I'm not sure if I really want to do any more of these on my own accord, so if anymore are made, they will have to be made by commission.
However, I probably won't be taking any of them any time soon as I'd like to focus on animation commissions for the time being.

Either way, Derpy's dick is THICK! The commissioner even got lucky and I decided to allow them to have it thicker than Dash. :P

Hope ya like!! :3
