What hits me straight away is how good the synths sound and true to the 80's vibe they are. The percussion also emphasize and enhance the mix a lot. The rendition of Magical Sound Shower is great. I like the personal touches a lot. I think this is definitely ready for submission. I so want to offer some more substantial feedback but this sounds AWESOME. The expression on the leads is fantastic and the mix is, as usual, full, warm and balanced. With this, the sources are interwoven well and there is cohesion as you refer back to previously used sources, bar MSS but that's fine as its more like a bridge. It is really well melded in btw.
My only comment would be on the ending. I feel that more tension could be built up before finish. Whether you use higher octaves before the final repeat of the main melody or by dropping the bass for a bar or two, I think you could have a more......definite ending. Its a tiny tiny point that is more personal opinion than anything else.
Great stuff bud, I really like it
