Tired, Bored and Alone (Light and Shading Test)

I wanted to see and test how well I Shade and do Lighting Digitally and, personally I think it went very well.
This was suppose to be posted about a week ago, but because I wanted to test my Shading and Lighting so there was a longer delay for it.
If you have any tips and tricks for me for shading and lighting, I am more than happy to take them.

This took about 5-8 hours to outline and colour in different sessions and 5-8 to Shaded and Light in different sessions
