Ok. In the first video, it starts off in Eminor, with some related chords, with the somber melody which works.
Then modulates at around 35 seconds to B minor. You could offer more development in the LH, but I think it works OK. Near the end, you seem to want to start another section which is a bit faster, but then it just concludes quite quickly. It sounds like you are just starting to experiment with composing, and you have some ideas which could be developed further.
The second video, it seems, has the first half pretty much fully taken from Gounod's version of Bach's Prelude #1 WTC, though simplified. It can be useful to imitate pieces that inspire you to get started composing. The second half, where you deviate from the source material, I don't find very interesting.
I would say, keep experimenting , especially if you enjoy the process.
