considering that this is a very old manipulation and I also redid this at another stage (hence the version 2) I can't say exactly, it's roughly 2-3 hours of work. I mean, if you know beforehand where you are going to put all the effects like in a tutorial it would be 40min but since you have to create it first and play with ideas, the time multiplies.
wow thanks! actually i'm a beginner in Photoshop - we're taught how to do composings etc. in school. But i find it kind of hard to decide what i want to do to any picture. It's like not the lack of creativity, but i can't focus myself on one idea. So if you could tell me how to get like a rythm for actually learning composing/digital art in photoshop, I'd be soo thankful! Because i really enjoy all of your artworks^^
