Photorealistic Ball-Point pen drawings

Found this on the net, figured someone else might like them link

I would just throw them up on here, but some are NSFW(boobs).

I've never seen such good ink drawings, I mean, I've seen plenty of good ones, but these look true to life, just in blue.

The artist is Juan Fancisco Casas. His site doesn't seem like it has anything other than random Facebook-esque photos, and a few more amazing pen and ink drawings, also en español.

Those were really good. I especially like the part boobs

edited OP with his website and what I thought of it.

Those are pretty cool. I always find it interesting when people take the most unlikely medium to an extreme.
Not sure what I make of photorealism as a whole, but these seem a little more stylised than typical examples of that genre.
