I, for one, am quite fond of the new psuedodragon picture; it fits into the whole "draconic cat" personality. It's very content looking.
I wasn't fond of either the original blink dog or titan pictures, but I don't like the new ones very much either. The titan looks too, well, juvenile. And, as previously mentioned about the blink dog, it's time to put Old Yeller down.
It kind of irritates me that the inevitables and gith races have re-used art. It would irritate me more if they weren't really good pictures.
And I almost did a little gleeful dance for the demon and devil pictures. It's good to know that the fiends are still loved, and I really like the cornugon; very draconic.
Oh, and Spiteful Dwarf, I've used delvers. IMC, they're sort of like treants, except they take care of the dirt. Make sure it isn't over-mined, maintains nutrients, etc. And, of course, they say "hoom".
Demiurge out.
