you know you're a furry when all you draw is animal-related.
I can only draw architecture and copy a realistic drawing... somewhat.
I guess I'm too mathematical and drawing something with deliberate flaws sends me into unsurety overload. But I hope to try.
You know you're a furry when even if you tell no one you are into furry things, you really like those plushy slippers with your favourite animal on it you saw in the store.
