3 is my favorite just for the fact that I love Sonic Spinball, And you just made my day. Every thing about that mix, in my opinion, is perfect with the exception of a few finishing touches I'm sure you have in mind already.
(Now do Toxic Caves please anybody.)
1,4 And 6 are all very heavy on the star wars which I personally like, I just wish 4 And 6 were eligible to be submitted. However if you were to rework them(hehe say that 5x fast) to where the star wars wasn't so blatant and more like an "inspiration" you might get away with it. But still I like them the way they are. So even if you can't submit them when your done let me know..
Any way 1 was good I liked it a lot, only thing I have to say on that one is that you could,as Tables stated already, tie this one in with 6 and make into a two part tack or just give all the love at once in one track.
5 Was in that the first almost half of it was nice and soothing then it turned into a game show, I mean don't get me wrong I liked the change up half way though. Very nicely done.
Only thing I have to say about 2 is the Forest of Illusion part was my personal favorite part, it was just so good I say do mix with that alone. The mix as whole is phenomenal.
These are all really EPIC mixes can't wait till there done, keep up the good work.
