Love that you entered a real recording, did not expect that. Acoustic solo instruments are regularly a hassle to record, so hats off to you for pulling of an enjoyable performance!
I think it sounds a bit dry and direct, maybe that's intentional. But try a little (or a lot *g*) of reverb on your tracks or on the master and see if you like it. This might just be the missing thing you are looking for, it normally mellows everything out a bit and blends the whole arrangement together.
Also not rating this entry because of cover, but I really enjoyed it!
