Keys in the Cogs of Life

I joined Illustration Friday quite some time ago and each week, look at the theme in my inbox and think,,"I should do something for this one!". Somehow I never have though, maybe because of "newbie nerves" LOL
So this week's theme arrived and it was EQUIPMENT
I had just finished this piece a couple of weeks ago and thought maybe I would use it. Equipment also means machinery so it seems to fit.
A little note about this piece, it is an abstract meant to loosely represent MY life, won't go into full details since I don't need to write a book here, but the 4 keys stand for my 3 children and grandson, who keep my cogs running!
I hope this fits in with the theme and that everyone enjoys it.
It is an 11x16 colored pencil piece.
