In need of help

[Shawnn]

I've been lurking the forums for quite a while, and I'm still trying to better myself at mixing. Help a beginner out please!

How could I make the guitar tone and drums sounds better? Advice on mixing such would be greatly appreciated.

Guitars > Revalver mk3(Gubbkuk's settings)
Drums > AD
Bass > Cakewalk bass

Thanks in advance.
