Terraria Pixel Art - MegaMan 2 Select Screen

My newest project.  Not in Photoshop, but instead a game.  I've been hooked on Terraria for the last few months.  My main world is post Moon Lord and I decided to try my hand at pixel art for the first time.  Knowing me I started out BIG!  This took roughly a week and is composed entirely of gemspark blocks and walls.  This is the view from the map.  I filled in the gaps in the mugshots after posting this.

EDIT: Now with full in-play close up air-hammer.deviantart.com/art/…
