Liking the Mercy and this last piece.
Really liking the design you did for Mercy
Things that stand out the most in both paintings are the hands. In your Akali piece, I like the hands in the previous wips than the ones in the final image. Mainly the way they are posed. The lighting in the last piece is a bit odd as well. I having a bit of a hard time understanding how the lighting is affecting the shapes.
Another thing I think you can work on is the hue variation in the skin. While color picking I noticed it flowed down in a single line so it gave off a weird feeling. Add so red in there.
Composition wise I like this piece. Love the red. I can tell what the materials are. Also this might be me but I like the masked version a bit more than the unmasked. Overall good work and I look forward to the next piece.
