thanks Art, much appreciated. my workflow always starts with either a 3D model or photography (the latter in 8 out of 10 cases)... and then i just add more and more photographic elements in Photoshop.
in the Idiot March image for example, the ground layer is a photo i shot out of an airplane window somewhere over the desert, and the entire army is a simple 3D model duplicated a few hundred times. the flames, smoke, fog, textures and color correction are all Photoshop.
oftentimes i'll paint random blotches on a piece of paper and scan it, then throw bits and pieces onto the composition, etc.... just keep going until it's where i want to be i guess.
i'll do a little breakdown of an image if you're interested, just pick one (although i'm not sure if it's ok to show original photos of actual people on the forum).
