How can i improve my Guitar sound

you probably don't want to be putting verb on the guitars. As for compression, distorted guitars are by their very nature already compressed so you should try avoiding adding more. Chances are additional compression would be added later during final mix (bus compression, etc). Instead, try panning your 2 tracks out a little further, more like 80% L/R. That will open up more space in the center for the bass. Also, can't tell if there is any bass in the clip you posted (if not post one with the bass added). You'll want to use a high pass on the guitars, start around 80 and adjust until it sounds like your bass is providing more of the lows you are trying to achieve with the guitars and then see how it sounds
