Here's a slightly different version of the turret I did a year and a bit ago. This one is a lot more optimized and cleaned up. Still a few things I don't like about it. But I limited myself to redo this in the same time as I did the original, which was 3 hours or so. In that same time I produced this one, which is 10% of the polys as my original one was. So I'm quite happy with it.

Very nice, looks very functional. Are you going to texture it?
