For a couple of years I did a little weekly illustration project called Freakin' Monsters. The purpose of which, was to draw weird and cute shit.
It was meant as a bit of a challenge though — to draw quickly and from my braincase. I ended up doing mostly fan art though, and taking ages, but I still had a lot of fun doing them and I got some gigs out of them too. So all in all, it wasn't a total waste of time.
