The sharp, square shoulders clash with the character design and presumable fabric choice, makes for unpleasant silhouette so I'd soften those but still keep the overall "square" shape you're going for.

This is more style critique but imo the head proportions feel a little too squashed and flat on top. It might need a small vertical scale upwards and/or rounding the top of the head in the center like a real head. Quick and dirty resize, I think the happy medium is somewhere closer to yours but slightly taller.

From drawing anatomy, I start with the eyes or the brow ridge roughly on the midpoint between the chin and top of the head for realistic/semi realism. Different styles play with this proportion but it felt a bit too short on the top side in the closeup.

If you analyze faces by making a triangle between the bottom of the lips and outer eye bounds, that triangle is a small portion of the overall frontal facial plane view. The cheek planes are rather large which I think could be balanced out by more mass in the brain case or lowering the eyes/nose a little and scaling down. As they are now, it indicates to our human senses a much larger skull so it looks a bit uncanny although it does indicate the character's presumed personality.
