My apologies for being so quiet. I've been doing a lot of work under non-disclosure agreements so I haven't had much available to actually post online. Thankfully, the latest Hearthstone card set, titled The Grand Tournament, has been released and I painted a few cards images for it. The first painting, Recruiter, is shown above. I'll post the second tomorrow.
This was drawn and painted entirely in Photoshop. I started in black and white and worked my way up to color, using a variety of digital brushes.
