Depth in blue

This is my first attempt colouring a portrait, think it turned out well, though there could be more depth in it. Was afraid I would've ruined it if I tried. The bacground didn't turn out as I wanted it too, but well enough for what media I had available.

The drawing is a little better in real life, but that's normal I guess

I used mixed old colour pencils from I was little, Derwent for skin tone, derwent graphic pencils and Staedtler....toilet paper as well for blending

This is drawn for and the reference is from
