I just did this. Took me about an hour. It was easy to do on Adobe Photoshop, the thing I'm impressed with is the idea. I just fancied making a landscape but with darker colours and more unusual unnatural colours for such an otherwise natural picture. I added the butterflies at the end because I thought it needed a little bit more to finish it off. I eventually put white butterflies on the picture too to make it look like a battle between good and evil. I'm actually quite impressed with the outcome! there's a black border around it so that's why some of the swirls seem to go off the picture. Here it is:
Any comments would be greatly appreciated. Thanks
