Your render has caught the basic predatory nature of this beast. I am not an artist but I respect your ability in this art form. Excellent work. An amazing and frightening sight to come face to face with. I remember a interesting fact about the Hind's cockpit that reflects the Soviet's attention to design criteria. They incorporated an electric fan that was mounted to blow cool air onto the pilots face. The reason given was that they found that this had a relaxing and calming effect on the pilot in high stress situation.
Truly wicked. Imagine... "hey, what's that in the rear view mirror??" Damn. Sweet and very detailed. The only thing that prevents it from being photorealistic is the shininess, the absence of dirt I mean
