Digital portrait painting

Hello everyone, today i am here to share a new digital portrait painting with you all.
today i was trying to practice drawing male head and this is the end result of that practice.
normally i was just sketching. i sketched a few more heads before this one. but then i felt like coloring this one.
and therefore i started painting.
it is a bit messy because nothing was planned. i just kept making mistakes and then kept fixing them, or at least tried to fix them.

after a lot of pen strokes this is the result that came out today.
added some glowy bits at the end to glow up the drawing.

here are some process shots:
