I'm training in animating skills for game design. Here is a completely random scene. First I draw a desert landscape (training my dithering skills ahah, it was long...) And then I wanted to integrate this helicopter.

I'm thinking of prolongating this anim by adding a character that would take the rope to exit the screen, like a finishing level scene.

I'd like some feedbacks on the background as well as the animation. I think it could be smoother but I cannot figure out how to improve it...

Thanks in advance for your help !
