Jesus Salas (macuy19 at deviantart.com sent me the original high res inks to this one to have some fun with. Pencils are by Juan Lopez (mistermoster at deviantart.com). I was trying to get a 1930's feel for the whole image. You know, that nice sepia sort of colour that they had in the movie of the Rocketeer.

Apparently Dave Stevens (creator of the Rocketeer) has also seen this and loves it! Yay me! (So do Jesus and Juan by the way!)

To answer some common questions asked elsewhere: Background is a bunch of layers with different settings using the glitteratto plugin from flamingpear.com set to screen mode combined with a bunch of gradient layers set to multiply to give it some depth. came ou nicely IMO. The smoke trail is just some squiggles with the paintbrush in photoshop, and a some smudging.

cheers
