taavi, that's quite nice, nice angles there
wygiuxx, it's fine, needs a bit of soften on those borders. No AA on that front tho, from another game me thinks (?) The pic is well done, just needed some more work on it
Cut the wheel out and then stretch and rotate it to make it more of a circle. Highlight or select (so you get the dotted line round the edge of it) the wheel, then apply your radial blur. Resize it back to how it was and repeat for the other wheel.
It helps if you keep a mental note of how much you stretch and rotate the wheel, that way you can get it exactly back to how it was.
One i had a go at, can someone have a go at removing those annoying little blobs on the left? xD If you fancy a go with this pic i posted it on the edit my pictures thread.
