Marlonjohn, Eelco and Arran, thanks for comments

The cityscape is an image with heavy photoshop work to remove buildings and boats along the Thames,and there were alot, hehe.

The horizon was a composite of 2 sets of clouds incorporated and hand painted to fill in the gaps on the cityscape.

I tried creating more realistic smoke in Maya but I still need a lot of practice with dynamics.

The look I achieved I think was mostly due to the lighting I used and rendering in layers. I had one point light as my main shadow then used an area light underneath and above each aircraft to create some softer shadows.

Arran, I didn't want a great deal of damage inflicted, it's still early in the war. However I could have certainly toned down the smoke a bit.

Cheers!
