The drum sounds themselves aren't bad, no, I didn't mean to sound like that. To my ears, it just doesn't sound quite like a true matching-piece kit. It's kind of hard to explain. Take some 'verb off of that snare and get some high-end snap into it and it'll mesh with the rest of the drums better. The kick could also use a little less low end. A bass track would definitely aid your cause, orange tree samples makes a neat VST instrument if that's the flavor of bass you're looking for. Maybe cut some low mids (roughly between 300-650hz) out of the guitar tone and give it some 800hz warmth. How did you make that sound at roughly 0:26~0:27?
