I love to work on a tight deadline - the stress brings the best ideas quickly as I know I will not have time to waste my energy on ones only half good. Even a sketch of the dog of my hairdresser proved to be useful. My first illustration in a big, women glossy and great fun (what you see is just a little drawing I made this morning, not the comissioned thing).
However I might have to spend my fee on an eyebags concealer...
