Those spikes he shoots at you? Jump in the air and dodge them sideways. It's the easiest way to not get hit.
The first melee combo you got hit by was also a skill issue. You only started blocking after the first attack.
Also, why the hell aren't you healing between attacks?
All of this doesn't really matter, btw. Your level is way too low to comfortably beat him.
Go do your main quest instead and gain some more levels.
