He is Blue.
I like the almost colored gray scale aspect of this with the low bit back ground gives a fun original Game Boy effect to the piece.
The fist in the lower right is a little disconcertingly large, but otherwise I think you captured the proportion of the dace an cowl quite well, because man bruce does have chin for days in the 90s show.
Also, I think it's is worth noting that you did quite well with the shadow work.
Thank you for making this.
