This is one I drew a few years ago in honor of BItcoin Pizza Day. I've been accused of uploading a photograph. If you look closely though, You can see a few lines and imperfections. I love the dough color and the edge of the crust. I don't think I will say how much time I spent on this, lol. I will say that the price of BTC moved up and down a few times in $300-$600 increments.
Hope you like it.
