Don't cock it up... Who cares!
I have started attending a live model sketch group once a week Wednesday nights.
I've always been a bit insecure about my sketching, and knowing myself self well tend to be competitive at anything new I try my hand at.
Surprisingly though I don't give two hoots when I go sketch. It is in itself therapeutic and something I yearn to revisit each week while checking my ego at the door.
Life is full of surprises...
