Cyberguy's Bucket O' Pixels.

[Cyberguy64]

The legs seem too high up. From what I remember(i may be wrong), Spectre night is rather slender and longer. By having the leg/leg armor he has a somewhat bulky appearance.

The bulk is an illusion of his robes and the fact he floats in a semi-sitting posture. He looks similarly bulky in Shovel Knight until you beat him and knock his robes off to reveal what a twig he is underneath.
