Well, I've got to confess I found the length to be a bit daunting. I did watch the first 20 minutes so far. It's interesting viewing Berserk images accompanied by piano music! Kind of evoked the feeling of a memory at times. Also made me think of those old time silent movie theaters where the film would have a pianist playing the music.
Your playing is really good!
Sometimes the images felt a little disjointed to me. Particularly in the opening song they just seemed a bit random at times. After that they seem to have a better flow and I do like your choice of images in some places. Guess this probably wasn't all that helpful, but those were my impressions. Welcome to the forum!
Update: I finished watching/listening. Your choice of songs and your execution of them fit the scenes very well. The music really carried me along through the narrative. Your choice of images through most of this is good. The ending is a bit random, image-wise, but I'm sure you're aware of that.
I can tell that a lot of heart went into making this and it shows. You are a talented pianist! I really enjoyed this. Thank you!
