Digital color on pencil drawing

this was a pencil drawing that i drew more than a year ago. i colored it two so many times ago. sharing them now because i love this drawings
i colored it in photoshop
Normally i would use clip studio paint but photoshop had a few more advantages.

First i imported the photograph, resized it and then used levels to brighten it up so i only have a high contrasted black lines and white areas.

Then started painting as though i finished sketch and now coloring time.

Here are the process shots of the digital part of this drawing:
