I love the over-the-top coloration.
I love your vibrant colors and emotion :)
I do notice that his left eye proportion and position is off. It seems a little too small and not shaped at a roughly right angle form to show that it's a 3/4 view.
You are mostly right about the eye. But in this model, his eye's over the lid on that side is just that extra bit slooped, and smaller naturally.
Maybe I know too much. Sometimes knowing your models can change how you draw them, versus coming in cold to the season. I think that may have stumped me a bit.
Thanks for the critique.
All the best,
