Jonan is Rainbows - exercise

I'm gonna try reeeeally hard not to snicker too much at the title.

So I stole this exercise/challenge from ! Here is the blank one: [link]

This time, it's Jonan! A ridiculously gaunt, stupidly arrogant necromancer, and one of three main protagonists in that RuneWriters story I keep posting stuff for.

Tareth's, Jonan's, and Severian's Rainbow challenges were all drawn one right after the other, and this was the last one I did. I expected that Jonan would be the easiest because, quite frankly, I adore drawing his face, but I actually ran into the most trouble on his (you guessed it) straight-on view, as I suddenly realised I have never drawn him from this angle and had no idea what his hair would even LOOK like from the front.
So this is a guess.

Upwards 3/4th is my personal favourite.

_{I wonder if I have ever explained that runewriters naturally get vibrantly-tipped hair, or if everyone has been assuming that all my magic-users dye their hair ridiculous colours?}

Critique and helpful observations are welcome~!
