The Minotaur

I've been working the whole morning on this picture, it almost drove me crazy and I think my hand is going to fall off any minute.
Now that I finished the Minotaur I'll have to redraw the mermaid, because the lines in that picture are much too smooth and it's too detailed. But right now I don't know if I'll do a completely new drawing or try and fix the old one. 
Also I still haven't decided on the other pictures yet, but it seems like there's going to be some red in the artbook.
Now my hand needs some rest. :(
