Without having listened (I don't listen to MP3's), here are some generalized ideas for any sound which is too "in your face".
1) Panning - Where are they panned. Are they right down the middle, then spread them out. This will go a long way towards removing some of the focus on an instrument.
2) Reverb - Most home recordists under use reverb. By a lot. The trick to using reverb is to make it less noticeable, and to insure that it does not build up. There are a couple of tools which are very important when using EQ. Experiment with different pre-delay settings. This will basically move the source closer or further in the depth axis. Next, when you use a lot of reverb, you tend to get a lot of unwanted bass buildup. This is bad. Instead of using less reverb, put an EQ inline before the reverb unit, and use a heavy high pass filter (low cut filter)If you remove almost everything below 800 Hz, you will relieve yourself of the bass buildup, and you can use a lot more reverb without it being particularly noticeable, which is very useful.
3) Delay - experiment with it. Send a dry signal to one side, and a delayed signal to the other, than experiment with different settings on the delay. Try different oscillators. Experiment, and have fun.
