I think shading is the least of the problem. They should take their time with linework and refine it a bit more to be honest. They should also trade out that dithered backdrop for one that matches the shading style hes using for the character.
Take careful with banding, a common mistake of make a line and then another with the same length, but just with another color and the shading seems incorrect in some regions like in burst and abs.
