Catching up on Facebook nonsense this morning, I came across a little advertisement for 'Tips for Illustrators' or something to that effect. I clicked through to the fan page, then continued on through to their main site.
There's all sorts of helpful things - podcasts, tutorials, outside links and tips, as well as inspiration for all sorts of aspiring illustrators.
Escape from Illustration Island. Poxy name, but before you cringe and click it closed, take a look at some of the treats it has in store for you.
