This concept/matte was created during a demonstration of speedpainting which later evolved to a fullblown concept/mattepainting. The painting took about 19h to paint. Painted from scratch in PS and refs used for texture.

I have been working like an insane, i think i need some time out. Gonna take a few days rest after this one.

Cheers
