First image is well done. Typical gaming style. (Glow, much :P)
Second image is more "new starters". (You miss glow, to "blend" the colors a little. It's so "direct". With not "flow".)
I don't think some rate will say how good/bad you're images are.
Image 1: Very nice, it's a bit classical style from what I have seen around. (But not on MPGH :P)
Image 2: Seen it so much, that it's nothing I would go: Woahhh.
