Good, steady and even playing!
I think you can get a rounder or "warmer" sound on the first string with some adjustment to whatever you do with your nails, it could be the shape of the nails, the act of polishing in steps up to a fine shine, or it could just be how you plant your fingers on the strings and make your strokes.
The notes on the 2nd and 3rd strings are sounding very nice, and it's definitely possible to get the higher notes on the 1st string to have that quality to them. Read up on tone production and experiment a bit if you need, what works for you is not necessarily what works for somebody else.
That's probably the only thing I'd change on this one!
