Apparently it takes forever for it to be approved if that was the case xD.
is a good one, I like it.
but, how @DoctorDRG says.
why you didn't post those liberation discharges sprites in one submition(?).
just 4 submitions will take more time to aprove than only 1. 
Rules quote:
"All pixel art is approved by a Pixel Joint admin to keep the gallery free from hardcore porn, spamming, hate speech and doodles. You can submit as many pixel art pieces as you want at a time, but please note that only five pieces will be approved per day per pixel artist to prevent spamming. So if you submit 20 works it will take 4 days for all the pieces to all be activated. In addition to the standard terms of use there are a few guidelines you should read over before submitting pixel art:"
Nice pixelling, though the four Liberation Discharge characters could be submitted as one piece, no?
ahaha sorrry D-jinn xD.
