I hope that feeling of 'since no one is buying my art anyway' is going to FUEL your motivation to improve your art.

I have been to your stage, currently, I am glad that I took the step to improve my art.
I am confident that the people in Menewsha would be willing to send you pointers around.
In the rare occasion if you did not receive any reply/respond, it is not because we are not helpful/selfish. It is merely just... slow forum. Honestly, I don't look into this part of forum frequently... or at all.

Whichever way, you have my moral support.
