Wow, great pics Cabo! I'm impressed!
The one thing that gets to me though is that: maybe it's your camera, or your graphics program, but something is just compressing the hell out of those pictures. When I'm working on something in photoshop, I usually save it as a .tiff file (no compression), and then when it's finally done I save another copy as a .jpg file (so I can upload it and not have it be huge)
You should go on deviantart if your looking for a website or something.
/edit: Nevermind, it was just the fairyland picture that was really compressed. The rest aren't too bad.
