Who’s the artist that drew the art on pages 148 and 220 of the PHB?

Anyone know the name of the artist or artists that drew the art on page 148 and 220 in the Player’s Handbook? I know there’s a list of artists in the credits, but looking through it, I haven’t been able to find that art specifically on any of their online portfolios.

Also, does anyone know if there exist uncropped versions of said art, and where you might find them?
