Personally I would maybe EQ the guitar a bit better they are feeling really sharp. Were you using an amp sim on your DAW or is this recorded from an amp? Sometimes guitar rig etc give off a really sharp tone. You should research EQ shaping and sweeping techniques which will help alot! Apart from that the song sounds pretty good 

 I agree with 
guitarded2 with the velocity on the drums...maybe possibly add in some reverb or delay to give the drums some more space.
