Here is a nice cavegirl with a spear and vine rope. She is a typical Hollywood busty shape but at least she isn't a blonde. Actually, many of the cavegirls in my cavegirl art folder seem to have black hair, which is more historically accurate as blonde hair only appeared quite recently as a result of a mutation.
The thing I like about this picture is that she has a proper, practical length spear, not like some of the silly little three foot ones we have seen in some previous illustrations.
Here is another picture by the same artist. I think she is pretty cute, well drawn, with a good fur bikini (I like the teeth on her bikini string!) and realistic looking weapons.
So I'd giver her 8/10
