Welcome to PS. You play well but there's things that need be improved before these recordings could be exposed to the world-wide audience.
First is the sound quality. Your piano doesn't seem a bad instrument but the recording sounds rather muffled and (unless my ears deceive me) a bit biased towards one channel.
I've never heard any of these pieces, so nothing to compare it to. Some nitpicks on the playing:
Heller - You must make up your mind on how to play these 2-against-3 figures. The score is not clear if they're meant to be 2-3, or that the last notes should come together. Either way would be ok I guess, but be consistent and convincing. If you decide on 2-against-3, then you must really practice that
particular poly-rhythm a lot more. It is not a very strong piece and you need to give it your best shot.
Gounod - Needs a firmer tone, less pedal, and more conviction. It's not a strong piece either and you need to make people believe you believe in it
The weaker the piece, the harder you need to work on it to make it worthwhile to the listener.
Gershwin - A fun piece but it sounds rather too timid. More schwung and fun, snap and bite please.
I've no doubt you can make a hell of a lot more of these pieces with some good polishing. I hope you can get some better recording equipment. Maybe
also open the lid of the piano (it's an upright isn't it ?) It takes some experimenting to get an acceptable recording sound.
Good to see you took care of the file names and ID3 tags. If you had not omitted the compose name in two if the Title fields they'd have been perfect
I hope these tips help you along.
