Something bothers me in the front perspective.
The helicopter's front seems a different direction of the body to me.
But, good job.
Thanks for the comments. I modify the movement of the sprite and i think that now is better.
very nice animation but the movement "forward-behind" i'ts weird imho...
I agree with Paulo, the front window looks as if in 2 perspective from the side while the rest is isometrical. Also I think the chopper should move up and down but not left and right
