I recently got my hands on one of these as well. I figured that for a couple of €, you couldn't go wrong and I was not disappointed. It absolutely is a cracking sculpt and the pose just spoke to me.
However; I am in the middle of converting him into Khârn the Betrayer (just because I can) and I soon found that these new, single-pose, types of GW minis might be beautiful as is, but they're female dogs when it comes to converting them.
Nothing I can't handle, but when everything is integrated, it's impossible to do even a mild repose of these guys without cutting, hacking and resculpting. And then you've got to make sure the flow of the anatomy is not fouled up by your handiwork.
It does not help that this particular guy is absolutely gigantic either. I mean; he dwarfs even biggerized Terminators! So spliced-in parts are all out of proportion and need adjustments themselves.
Just count yourself lucky to have decided to paint him as he comes on the sprue...

Your paintjob is outstanding though! The skintones you've achieved are excellent and the rest is obviously wonderful too.
So; a great sculpt
and a fantastic paintjob. That makes for one stellar miniature for sure!
