Primaris Ultramarine

Derwent pastel pencil drawing of a primaris Ultramarine to see how that could turn out, reasonably happy, still see some inconsistencies, but meh.
This is my first go at a Derwent Pastel Pencil drawing for real.
I found a pic online of this Ultramarines painted helmet, so yes, the original looks better than this, and isn't even 1cm tall, and yeah, that's scary.
I think i did added the mohawk on top myself.
Size, A4.
