I would contact Aron, or look at the photo a day thread and see if there are ones you would like to buy from the user. See a photo you like and then pm the guy and see if he will sell you a copy.
For artwork, look at Larry Zach- maybe just a strong sense of nostalgia but that guy does some incredible work if you ask me. Aron's pictures are damn good as well, depends what style you prefer.
Check out Carl Sams. Really good dude, shared a lot with me about outdoor photography as a kid. One of the best pure wildlife photographers I've ever seen.
If you are looking for great wildlife photography check out Don Jones. He shoots all wild animals; no captive game farm stuff. He is a great guy and fun to chat with. He shoots a lot for hunting magazines and such.
