Ah, damn.

I was pretty clueless about this image. I think most of the time went into staring at it and thinking about what I could add/change to enhance the image.
In the end I gave up.

It's based on a speedpainting and I finally found the time to finish it up.
I pretty much like the lighting and values, but content-wise, it's weak...
The tanks were fun, so were the copters. I could reuse those concepts in another image maybe...

PS 7, 12 h, no ref., 6k px wide.

Don't have much time for personal artwork at the moment...
