Hell Yea, Aqua Planet!!
Alright man!! I love sonic covers of all shapes and sizes, sonic is the shit dude. So good pick. And your melody work was excellent. Love the strings jammin' out up there so good work with that. I also really like the jazzy feel, haha! So good work addin' that in as well, very impressive.
But, there were a few problems for me. One is your drum loop is never changing, I'd say work on changing with the different themes of the song. And it doesn't have to change that much, just a little bit. You've gotta keep the interest in your drums or else you've gotta turn 'em down. I'd say turn the drums hit rate down all together, they seem to overpower a little bit. Also, you should throw a strong acoustic jazz bass in here. Now then you'd be going somewhere. That would make this an excellent jazzy cover of Sonic!!
Good idea man, can't wait to hear your next work. =)
