These both look like photo-collage rather than a lot of digital painting work. We could give it a try. It is kind of hard to do the copy part of the assignment on photo based things. Pick a portion of the girl with trees and cloud to use for the copy. Then you would need to get your own photo of girl, cloud, and trees and then we can look at how to get them together.
The digital painting one is linked to a site not in the above 2 images. I have been fairly sick, sorry for the lack of communication...better now, will knock out the requisite projects asap.
