That is so realistic it jumps off the canvas so to speak. The flower looks like one of those plant-animal hybrids. You come up with a image that is just a true marvel. It's like taking a trip to a planet in the future and seeing such a thing like that and get visually blown away. Totally awesome.
Yes and no. It depends on your level of experience with graphics programs. But the nice thing is you can download it for free at Fractalforums.com. You can find a lot of tutorials on Fractalforums and here on Deviantart that will help get you started. The rest just comes with lots and lots of practice and exploration. That is why I and so many others enjoy it so much...its always an adventure!
