hey guys what do you think about this Tips and comment are appreciate

some shading on the eye thingy
just add one or two streaks of diagonal highlights if you know what a mean
also i think the eye piece is too wide

how to add glow to my head for gimp?

The back bit was unnecessary,
but overall okay,
7/10

Duplicate what you want on a new layer, then add a generous amount of gaussian blur.
Also, it's a nice head, but as said already, the eyepiece is waaaaay too huge.

i know i'll fix it later
