I like all the helicopters. The Skycrane version looks good and I like the Puma meets Mil-10 look of these. The only criticism I have is that the tail rotor is too high, you could safely lower it quite a bit. At the moment it sticks out as oversized.
It's based off of the Westland Westminster (which is where the overall body shape, as well as the main and tail rotor come from. I'm going to attempt to do a smaller one, but I might stick with this one.
