Help with a non color drawing

[twin frost]

Can someone help me, id rather you dm me but I need help on my drawing 😭
I suck at shading and hair, and eyes 😭
I'm trying to make an aura come from his eyes and his hair look like its glowing, but I'm not using colors, I need to work on those

Do you have a reference to better show what you want to make?
