Stuck in a rut & need advice!

Hey guys/girls

I’ve been uploading to Envato for a little while & 5 tracks currently in the store, however, my 2 recent submissions have both been hard rejected and I’m struggling to understand why! here’s the latest can anyone shed any light on this for me?

Nice composition but the piano sound is not very convincing.

I don’t think its the piano is fake like @Audioland says. I think its because its only piano and it has that growling dirty synth, not that commercial value. Its of course a nice piece and would fit many movies and videos, but its pretty specific. You could make something with a more catchy theme, and clear melody, not just like full on piano. hope this sounds clear.
