A Handful of Illustrations

I've never really posted an art thread before, but I enjoy doing fantasy artwork, especially heavily environmental pieces. This stuff is digital, with the exception of the amphibian woman, who was done with pen-and-ink. I uploaded these as attachments since I'm thinking of restructuring my website soon.
I'm not a professional although I love doing fantasy/scifi illustrations. The link to my website's in my sig, but you can also find my personal gallery at http://www.heavyartilleryrpg.com. I mention this because not all of the images from the other website are in my personal gallery - and vice versa. Critiques and suggestions are welcome.

Edit:
I realized that you can't see the detail in the last image very well. Here's a link to a larger image:

One last attachment that couldn't fit in the last post....

Nice work, I appreciate that they're full illustrations with backgrounds, and not just characters. I like the creepy vibe of the lich pic.

Thanks!

Currently working on more - well, I'm always working on more...

Nice pictures. I especially like Demeter.
