Entry 1 had promise, but it's an unfinished product, especially with the pure black background.
Entry 2 would have gotten my vote, but Rainbow Dash's colours turned out just so... bad. It need more care for such big details like your focus.
Entry 3 gets my vote, despite having blending problems, the result looks quite promising, and I could see some work actually done with it.
