Let's look at the current stage photo before listening to me talking about the tough stages that I went through.
So what happened is that when I put his arms to his body there are huge gaps between them. The left arm is easy cause it really is just a gap, but for the right arm there's an entire bit missing: I ended up sculpted his elbow with green stuff, look a bit odd but I don't think people would have suspected it. The second photo is a monochrome shot because I wanted to see if the sculpt is smooth enough.
