Right I understand now. Thanks very much for your helpful feedback.. I will be back 
I'm not sure if it's strictly against the rules, but some people here don't like the use of zoomed pixels in non-zoomed animation. It's a voting process, so I think a lot of it depends on the piece.
If you want to fast track approval, it helps to list the color count and remove any extra transparent area. I also found out (from complaints in my early pieces XD) that 1x-2x zoom is preferred to 3x because of the built-in zoom buttons, so keep that in mind for future pieces.
Well spotted! I didn't notice that stray pixel.
I drew the art at the pixel level, yeah, but the animation is indeed outside of the grid (though I didn't know this was against Pjoint's submission policy). I rendered the original art at 300% maginifaction, and then animated it at 100% magnification. Is this a bad practice in general?
Ah yes, the green specks are supposed to represent mould.. this is one of the earlier, more basic bows in the game :)
Is there a stray pixel near his elbow in the forward-most frame? I'm not sure if this will get approved because you are moving the top section out of the pixel grid, but it's clear you drew it at the pixel level. I actually really like those green accents on the bow, so I'm voting yes. =)
No problem, glad I could help. =)
