Alright, so here goes with my impression of your work:
First of all, I don’t mind the modelling in this work as it conveys a good action set-piece; blasting guns into helicopters in a desperate attempt to survive (assuming you were trapped or wounded in this “warzone.”)
It’s also clear to me with the setting that some serious shit has gone down with the smoke, shrapnel and general lack of sunlight thanks to the effect from the smoke. One must wonder if they’ll ever see the sun when the war is over.
You’ve put a lot of time into this, and it shows. Given the right budget, I can totally imagine this being a fan film or independent film production of sorts. So, from my POV, a very solid bit of work. Keep it up.
