i love this song in the game and it always amused me that it begins exactly like CT's forest theme and is also a forest theme.
your clean guitar sounds good but a little dull. I would add some middle or high end to it EQ wise to make it pop out more. You can't hear the attack of so a bit of 3K would help maybe. nice reverb.
at the beginning I think the lead guitar has perhaps too much high end, or one frequency sticking out between the 1K and 8K range that is really grating to the ear. slap a band EQ on it, turn the EQ up to 12 dbs boost, and move the frequency up and down until you find it. then narrow your Q and notch it. other than that it sounds good though, like the tone and playing.
can't tell if it's the same track or a separate track, but during the middle when the lead guitar goes lower, it's not as bad sounding.
The drums sound good...are those real drums? The playing and the sound of it them suggest they are. I would like some EQ on them too to make them "pop" more. HI hats/overheads need more sparkle, do a high shelf boost starting at maybe 8K for 2 dbs or so...
the kick and snare sound pretty good but I would like to have some more snap on the snare at around 8-9K and some more attack on the kick around 4-8k so you hear more than just the low end. a boost on 60 cycles on the kick wouldn't hurt probably.
bass sounds good.
also comparing to my latest track which is about -10 dbs rms, yours could stand be louder...if you're just starting out, don't worry about mastering and overall volume too much, but do some research into what mastering is and how to get your stuff louder without making it sound like crap.
my process on the master bus (based on a lot of reading and tutorials and experience is)
1) roll off the extreme lows (20 cycles) and extreme highs (20K+) using low pass and hi pass filter EQ
2) a bit of stereo widening and/or "Centering the bass in middle and throwing the highs on the sides" via T-racks quad image or waves center, etc.
3) linear EQ to notch nasty frequencies and sweeten good ones up to +2 or -2 DB (i like to cut 300 as that is the "muddy' frequency usually.)
4) saturation to add harmonics and smooth transients (sometimes)
5) 1 compressor that is just barely hitting to compress transients
6) 1 compressor compressing up to 2 dbs to, actually compress and glue the track together/make levels more stable
7) soft clipper to snap transients / do it so it barely saturates at all so it's not eating my song
brickwall limiter that is barely working, set on -.01 output so it never clips. this brings the final track up to the max volume.
i'm not a professional but try some of that and see where you end up. don't overdo it at first or you will screw things up. hehe.
