Very nice but it as a technical issue :(
When you bumped up in size after pixelling you did not have the right aspect ration and ended up withh cut pixels which is totally uncool to do.
When you have art to scale up after pixelling then you need to sclae using 'nearestneighbor' and in increments of 72dpi so the pixels reamin square.
Use the -+ syobols under the art to view. When you make a new output file use the 'edit it' link under the art to upload the new version and we'll add to your gallery.
If you need more info or help with pixelart output in Photoshop and general Phooshop settings for pixelling then just ask away or post in the forum where somewhere is a whole thread on PS and pixelart.
