Before posting any Pixelart go read the RULES
You should have read it anyway, as the Rules forum is clearly visible.
But we get people here who obviously don't read the rules and then wonder why they get banned when they are in violation with one of the rules.
One more thing to keep in mind: Pixelation comes with a zoom feature on all images inserted using the [img] tag. Click to zoom, shift/ctrl click to reduce zoom level by one, alt click to reset zoom. Please make use of it, and save your images at 100% zoom if it's not absolutely intended to be viewed at a higher zoom level.
So, read the rules, be nice and friendly and enjoy your stay.
