where's the sub/bass? :)
definitely needs some bass besides the kick. :) a nice low sub would be great.
try changing the string progression up every 16 bars. keep in the same key but just start at a different note and make a new pattern.
you already show a bit of alteration between string patterns by tapping it three times, which is good, but throwing out a new pattern would add even more interest. :)
I like it..nice work
Try a bit of variation on the beat instead of using the same one again and again, and look for better samples.
Will do aha
