Hello,

Smoke effect for shell impacts could  look a bit better, currently it looks a bit dull/vague... like some puffs..

Perhaps the smoke could be more animated, like clouds and black or grey smoke going up in the air... a bit more dynamic...

Currently it's just a bit dull looking. Especially from the new rocket tank on russian side... stukyaks or something...
dont know the name yet of it ;) :)

Additional idea:

Add a little bit of a shockwave effect, perhaps with shaders... make the graphics/view whirle a little or deform... 

Bye,
  Skybuck.
