It's a Botany Bay Cockroach, found around Sydney. It's in the group of burrowing cockroaches but isn't as specialised. I took it at the Sydney Museum on holidays: they had an exhibit with photography allowed! But thanks!
I had some trouble with my shitty Livebrush program, but I ACCIDENTALLY managed to convert one pic to a PNG format. Accidentally, mind. There's no colour, etc. or eraser and the program is just for amateur vector drawers but whatever. This the worse of 2 Whimsicotts, BTW.
EDIT: Realised I photo'd a couple of my pics. PHOTO'D. Lol but whatever.
