Apologies, missed the above, no no close mics on this recording.
Muzza.
Yes. This is your problem on this track.
The way I see it, you have four options: One, add a kik and snare sample to the track and painstakingly place them into your track. Two, reamp the guitars so that they have a similar ambiance to the drums. Three, scrap what you have and start again, this time with some mics relatively close to the kit in conjunction with your room mics. Four, move on, do the best you can with what you have and do better on your next try.
My recommendation would be the last of these options. Learning how to record and mix is a long process, and your early recordings are not going to offer you professional results. You've made a classic mistake, one that has been made by countless recordists and mixers. The good news is, you've learned from your mistake (we hope!). Close mic the drums in conjunction with your aggregate stereo mics. This will give you more room to operate on future projects.
That's not to say there aren't times to use only the aggregate stereo image, but while you're learning it's best to offer yourself some control.
If you DO choose the last option, try aggressively compressing the drums. Unfortunately, hardware compressors are much better for this, particularly as it relates to fixing things, but if that's not an option, try all of your plug-ins and see if any of them do the trick. Try a fast attack/fast release with a high ratio. If that doesn't do it for you, play with the attack and release ratios until it does something good and punchy. Use your EQ to boost the kik and snare (kik is going to be in the 100hz range, snare will be in the 2-3k range). If you put the EQ before the compressor, then your snare and kik EQ boosts will hit the compressor (especially if you're aggressive with the EQ). If you put the EQ boosts after the compressor, you'll get different results. Try it both ways. You might even end up with an EQ before the compressor AND after. You might also clear out some of the low mid buildup caused by your room. Try cutting the 200-300Hz range. And then, if you're liking that, try boosting 10k and above after the compressor to open them up a bit more. Be careful about that though, you don't want the drums to be unlistenably bright.
Those would be my recommendations.
Enjoy,
