new here - any directions on improving my pitchfork?

Hello!

I just uploaded my first asset.

It got 4.7 for the model score after following some "how to improve". (4.2 -> 4.7)

Now, I don't get any suggestions, but I'm still lower than 7.

What's the next step I should do?
(ie. what's the most critical thing that's hindering my model-score?)

ps: I can't find my asset when I browse through

Is there something very wrong with my asset?
