Hi rv,
I don't know your name so I will just refer to you by your username on the forum

I had a listen to both of these preludes by Scriabin. From what I heard, your playing sounds really smooth on both pieces. As far as the digital piano sound, I've heard far worse, this most be a newer model. I once had a cheap casio keyboard that had no touch response, it was no fun to play

. I don't have the score to this piece but listening back from :37-45 I think you could have really made more of what I believe to be a crescendo. The difference in dynamics from the start of that phrase in the end did not seem as dramatic as it could be.
The second piece is interesting. The opening reminds me of his later c# minor etude (op. 42 no. 5). I enjoyed the forte crescendo at :41 It seems the one advantage of a digital piano is if you play very loud it will not clip if it is recorded through the piano, whereas if you play loud on an acoustic you run the risk of distorting the sound. The c# sharp at the end has a nice sustain. I think I can hear it till the end.
Enjoyed listening to your recordings of these Scriabin preludes,
Riley
