Generally not bad, though i didn`t like 8-bit part of it. My favourite part is after 3:35. Do you have piano sheets for it?
I can say it because it (along with the list of pieces i`ve played) was just an explanation why i`m looking for music of particular style and instruments and what difficulty i can handle on piano. I`ve never made video of me playing, but maybe i`ll try it on my next performance.
Do you know how to load up 3rd party VSTs and layering samples to one group (the latter is beneficial when using a ton of one-shot .wav files)? Image-Line also has some really great YouTube tutorials on the basics like that.
Alchemy Player - I couldn't find a reliable download, so I uploaded mine into mediafire - CamelAudio is no more, sadly.

Also, hunt down ProtoPlasmTSM and AnviliaFree - they're pretty decent Pad synths that are free.
