I have to say a bit below average in this area. I can't skin. So kudoos to the author for getting a skin on the model. There's one skin included with the model, so CTF fans won't be able to use this one right out of the box. And good luck to you finding a place to slap that CTF decal on, the ass comes to mind although it might be neat to see CTF skins with a red and blue heart.
Some areas have some decent detail, under the head where it's been hacked off comes to mind.
You really get the idea that this guy was stitched together with no concern for aesthetic value. One thing that's really lacking however is overall shading. There are some very nicely shaded pieces in the skin, but no overall shading of the whole form. This is especially noticeable in the spine. The head is the best part of the skin with the detail being really sharp and the underside of that head is disgustingly good.
