Quality issues upload for illustrations

This needs some clean-up work. The cut-out is rather sloppy, there are several noticeable smudge marks outside the lines. And some of the lines are not connected properly. 

Why are you creating characters in Photoshop?  You should be using Illustrator for this kind of work.  Vectors are higher quality than rasters.  You’ll make more sales from vectors than you will with PNG files.

Read the 7-part section on Vector submission requirements in your Contributor User Guide. It starts here:

Check the outlines - there are stray bits of color outside the lines.

Bad cutout throughout. Always review your pngs behind a dark background to assure your cutouts or background removals are clean.
