EDIT: I got a MUCH better picture of this from my art teacher so I thought I'd re-upload.
Ta daaaaa. My self portrait! I have no idea how large this is but I do know that it took me roughly 68 hours and 30 mins to finish it.
It's me on the left and my younger sister on the right.
I apologize for the slight yellow tint - the lights in our house and yellow so that's how the picture came out.
It started off as a grid-drawing and this is the turn out.
Used pencils and Primacolor.
