Be careful with your pixel placement, k. You have talent and make creative things but skill and technique goes a long, long way. Most pieces in your gallery have some sloppy behaviour. Stray pixels, off-colored pixel here and there, etc. It kinda kills the work.
Here the tip of the middle finger has 2 missing pixels and an off-colored one. 2 grey ones (4th color) in the target. The target's white is a bit dirty and is where a sloppy look comes in. Another grey by the Asian characters...just watch these things in the future,k.
Its like your Marisa pixel. Cool and original but stray pixels on the outer transparent area diverts the eye and takes away. Or your hail girl. Another cool piece messed by being lazy and sloppy on the BG. If the BG was clean, precise and delibaterately pixelled it would be a gazillion times better looking and received.
Anyhoo, just keep at it, you've got talent 
Great looking piece only hampered by the several mis-placed pixels here and there.
That you for the advice :D
Yes, I have noticed some of those irritating off color pixels. I've been using a less than up to par program for creating transparency and it leads to these issues ;A; Hoping to install PS soon!
And yes, I must work to be less lazy! >w<;;
