Are you looking for tone or mix/production critique? First thing would be to redo the bass. I hate to say it, but the Fliptop sounds bad for anything "heavy," IMO. I've liked it on acoustic tracks I've worked on, but that's about it. Check out the TSE BOD plugin (freeware). Try blending the Fliptop and that into a buss. I'd also parallel compress the bass buss and add some distortion on the parallel channel (had luck with Juicy 77 - also freeware). That should take the abrasive bass tone away and still fill out the bottom end. The drum programming was fine, but I'd go on to actually set up the session with EZDrummer outputting to multiple channels so you have control over everything. There are plenty of YouTube videos describing how to route and EQ drums. Playing and guitars were good minus the lead towards the end sticking out. Also, use some buss compression to glue it all together.
