Thank you everybody.

I agree that there is a lack of coherence in the global picture: during development, game design leads the rest. Once I have coded inflammable environment, I need to draw something which can burn, there you got your tree... Implementation of different material colliders on certain enemies? Here comes a jetpack... On top of that, my drawing technique is not the same today as 3 months ago.

But be sure that when everything is set, I will come back to the composition, consider it as one piece and make it as homogeneous as possible.

Yes, sorry, I fixed the color pb.

So much awesomeness in only one point of the universe...

Thank you! He actually is the kinda fella you wanna have on your side at the bar, when comes the time to dance on the tables.
Unfortunately, in my game, you have to finish him in a clean headshot.
