The first guitar does not sound natural-like i can't imagine that sound coming out of an amplifier. I like the second guitar sound on the left, personally i would have swapped parts/tones-have the more muddy sound bolster the brighter sound rather than opposite. The last drum lick did not sound tight with the guitars. So i notice you only post short instrumental clips, are these parts of longer pieces? Or are you coming up with short pieces for specific purposes? Just curious.
