It was probably an honest mistake, other than the tattoo mishap it's a brilliantly executed piece. You sound really ungrateful that he spent so much time and effort on it, if I were him I'd be pretty annoyed if I'd made something like this for something and all they can do is complain.
I don't complain. I'm just naming what was wrong, and it's only markings plus they are really difficult. I do try to note what I see wrong on commissions done for me, so improvement can be made in case more would come.
Aside that, it's exactly what I wanted. After all, the main purpose of the commission was to see 's style. Not do it exactly to the point.
It was a bit of my fault. I wasn't able to provide proper reference until it was sketched (was waiting on newer ref for quite a long time). But I added Kyle on IM soon after I first noted him about commission in case anything would be unclear.
