Could I have help?

You seem to have upscaled your image by 200%, I assume to make it easier to see without zooming in. VGR asks that sprites be submitted at their native resolutions, no matter how small that may be. Here is a copy of your file reduced by 50%, it looks like the proper resolution to me, but you may want to look at it in an editor to make sure I haven't messed any pixels up by downsizing it.
