There are some guys here with more drum mixing experience. Mine is all digital as well, with Superior Drummer 2. Unless someone thinks you need the whole kit re-mixed, I would just work on the snare buses alone. Again though, I could be misled, and the snare is fine for this type of sound. If it were me, however, I would work that EQ, some compression, and fiddle with the bleed from the other mics. It just seems to be smack dead center (which is where it usually should be), but without any kind of body or fullness to the hits. Weak-sounding maybe? See what some other guys say;this is just the opinion of a guitar player and songwriter. Oh, and there might be some forums in here somewhere regarding drum/programmed drum mixing. They might be able to help more in detail if you decide on changing anything.
