Help!

I recently had my sprite sheet in queue and it got rejected because "This sheet does not currently meet our quality standards" So if anyone knows whats wrong with it, please reply: 

[Gors]

if it doesn't comply with the standards to quality, then it simply means that you have to work on it to become objectively better.

that's to say, those tiles are riddled with pillowshading, and too simple to be of actual use.

What is the picture of the sprite sheet even I can't see it.

Oh wow. I see what you meant by the sprites being too simple and pillowed.

Yeah, gonna have to side with Gors on this one OP. These are just so awful looking for the above reasons. I don't even know if there are any redeemable qualities in this. I would probably say maybe look at the glossary of spriting and perhaps brush up on some fundamental skills for art. I think doing both of those would help you tremendously.
