So, a simple request if I may ask. I see a lot of similar comments that amount to basically "Hey, you should just leave the art/writing/coding to (username)" and it's really kind of filling the forum with negativity.
Honesty without tact is cruelty. It's okay if you don't necessarily like someone's style, or if you prefer another style. You don't have to tell each and every person who submits anything that theirs isn't as good as someone else's.
If you have constructive criticism, that's okay, as long as you can convey it in a constructive matter. Otherwise, encourage, support, or just don't use the asset. We all have a similar goal: continuing to improve a game that we all enjoy.
So in short, help each other or at least keep discouragement to yourself. My own two cents.
