You probably first have to play with EQ on the piano you chose, you can work with some free pianos too, labs and foundations avec great stuff. I used Keyscape but only one presets and I EQ to boost some of the highs on one, panned the high notes on the right side between 30 to 60% and low notes on the left (like someone is playing left hand) and add a second layer of a piano with way more reverb but pretty low in volumes with that I have a good stereo balance and a little more upfront, if I have too I add a compressor to make it pop a little more.
