Critical Role - Vax'ildan fanart

The first of hopefully many postcard-sized artworks of Critical Role characters. I started with Vax'ildan from the first campaign as he's my favourite character.
The dagger is iridescent and tested my creativity in how to draw it and how to colour it.
I didn't want the background to be in focus at all, so I didn't add in any details, although I did make a source of light a little obvious.
This was a test of my skills, and I'm really happy with how this turned out.
