Some really nice stuff in here, I really like your latest Ice-X, very nice work, the chrome looks fantastic, keep it up
I really should start doing some of these myself, and btw, speed paintings tend to be anywhere from 10 mins to 3 hours to spend on it, it really depends on what the subject is, if you're doing a landscape, a group of characters and some kind of action, that can easily take 3 hours and still be considered a speed painting. Speedpainting, is basically painting quickly and not refining things to a perfectionist extent.
