Looks good so far, but I would recommend trying to finesse the edges of the inlay so they are a bit smoother. If you are anything like me, if you inlay it as is, it will look good to you for a few minutes, and then you'll notice the slight wiggles and wish you'd taken more time.
Definitely use what you have to practice, but I would suggest doing a few test inlay pieces until you feel you've cracked it, before attempting it on the guitar.
