Overall, it's not a bad idea for the song itself, but the implementation could have been even better. I recommend working on the dynamics of the songs in subsequent songs, as well as making brighter mastering if possible, this can be achieved using a regular Multiband Compressor, it's just one plug-in, but it will be able to set the energy in each of your songs.I also recommend downloading DirectWave libraries with all kinds of pianos and pads, they definitely sound much better than stock sounds.
I can also recommend you other tool packs for DW Sampler, I downloaded it all for fun not so long ago, but it turned out that they can even match the sound in the desktop version of FL.
