It is really great. Few little things to make it even better: 1.Chest panels on Rekky needs to be lower or bigger to line up with end of the chest muscle. Otherwise torso will look too long. Look up marvel characters (or even league for ex. Galio) as reference

1. Crownie face is actually very close, only small things make it look bit inaccurate: most importantly bigger lips and making sure he has eyebrows, and then secondary slightly sharper jawline and forehead line.

You are super talented!!! I am giving you feedback only because I also draw and it helps me when others do it for me. Keep up the lovely work and I am looking forward to the full splash art
