This is a skin based on Engineer from Team Fortress 2 that I made a few  months ago. If I recall correctly, I made it mostly to test the new skin layout added in 1.8, so it might be a bit overboard with the 2nd body layers. I have not logged in with this skin for a really long time so there might be issues, but I think  that it should be fine for the most part. I remember being really impressed with this skin, so I hope you like it as well.
