They're almost all from the same artist. Glen Skunk is his fursona, Oinuttah is his FA username (you can find more intense heart stuff at his alt account, Cardiobombastic).

I love his stuff.

TBH, if anyone is interested, I'd be down to draw more material. Let me know what you want and I'll squeeze it in on my free time.
(i also do commissions, so, if you want something guaranteed...)
