Wow, I forgot to vote.
Anyways, many sub-par submission this month.
9th is a bit decent. So is 17th; which could have been better with more subtle creativity and no scanlines.
The 10th is good. But I find the saturation and the colors too strong. Without the text, there is almost no focal at all and almost seems like an abstract tag.
The 6th is the better of all for this month. Nice flow, simple but smooth effects, well-done lightning and blending, an ok text and focal. Depth could be better but it's still remains the better of the group.
So I'll vote for 6th.
