Good grind man. For the 4 point perspective, I'd recommend to bring the top and bottom vanishing points a bit lower, closer to the character, which will give you a more defined 4 point style perspective for it. When you pull the vanishing points further, it "stretches" the perspective so to speak, in this case it barely applies the angle to the character.
Granted it's a rough exercice and the main point is to understand how the figure angle changes along with each vanishing point added. As long that objective is met, that's all good.
