Chess pieces of a dark sorcerer and his minions.
Pawn = zombie
Rook = skeleton
Knight = ghost
Bishop = necromancer
Queen = death knight
King = the Dark Lord
I absolutely love that skeleton. His tunic looks great and his expression to me suits his role as a kind of elite grunt.
You're good to go
I removed one of the colors.It should be fine now.
You have 17 colors since transparency technically counts as a color... I would suggest that you remove the transparency to keep within the challenge rules. Design a background with the colors you currently have.
