Look, mate. That comment will not fly far, and will just get you flamed to the Nether.

1. You spelled shading incorrectly. Honestly, I don't care, but the Internet will use whatever they can to argue.

2. Don't emphasize on words with caps.

3. Asking to delete a post will generally make them keep it up, depending on their tenacity.

4. The comment comes of rather rude; try saying it like "You may want to use less shading at x, x, and x. It's not of the best quality, in my opinion."

Good luck

Honestly? You use one of the most basic styles of shading, If you even shade at all, and it honestly looks terrible. ,_, Before you comment on someone insulting their style, try to make sure yours is at least half decent.
