SHADING.... A WORK IN PROGRESS

This week has so far been boring for me..
Probably because I've got lots of things weighing on my mind, plus stress at work...
So this morning, I decided to do something that will put me on a good mood..
So I picked up this piece of work I abandoned few weeks ago and do the finishing touches...

At the end, I realized I still need to work on my shading skillz....
I guess two things calms my soul:
music
drawing

What about you?
what activity/activities do you get involved in to reduce stress, worries or anxiety?
