Welcome to PJ   Don't feel disheartened by by the lil dude one not being approved, it's very difficult to get those into the gallery nowadays because people are kinda tired of them.
As for the plushie ninja, it's a cute start but I think you can fix this up a bit more   It looks a bit flat, and the somewhat pillow-shaded body doesn't match the direction of the lightsource (assuming the dark patch is a shadow being casted).  I don't think so much of that dithering pattern is necessary either.
Good luck fixing this up!

PS: I suggest hosting using a image hosting site to post your pictures directly in the forum so it's easier for people to zoom in and help you
