oh i see. so the resizing matters a lot, eh? actually i'm newbie here in pixel art field, i admit that i still need to learn much. just uploaded new version. hope it's the right one :O

 no i dont use photoshop to make this, but it's true that i turned this into jpg first. maybe i should just go with png. thanks a lot for the comments! probably will upload the right version tonight :)

ps: @FlyGuy, I am 'she' :p
