Solo piano music is one of the more difficult types of music to make, especially in online music communities like Newgrounds. The act of it is not difficult, rather the act of making it distinct. In case of this compo, it is also connecting with the art that poses an additional challenge.
In regards to this entry, I find it to be a perfectly satisfactory piano piece. The muted piano suits the muted tones of the art piece, and the composition gives that general sort of happy/sadness/hope feeling, which sounds like what you are going for. The problem I struggle with is that I think this piece is too surface level to be emotionally impactful. The chord progression and the way it's used here seem so typical that the piece feels like it could apply to a lot of situations and not just this specific piece of art it was inspired by. It could be the somber track where two lovers have to part ways against their will, background music at a restaurant or RPG stock piano music.
I also cannot get over how rough the transition is between 1:12 and 1:13. It feels like a forced key change and it really doesn't work for the nature of the piece.
Overall, this entry is okay. It fulfils the general emotion and connection to the art, but I don't really feel any connection further than that, sorry.
