This is in fact a great wallpaper. I must say I noticed these:

The clean cut vectorization of the scan, there are no unsightly edges over the lines, it is clean, nice, well done and very easy on the eyes, not like most vectors, eventually you will find that the colors are not as nice due to the rawness of it when applied to a wallpaper, you made this one well, the vector itself blends well with it, making it seem like a canvas.

The stock photo and manipulation applied is also wonderful, while it may not look like it is entirely well placed, it produces a sense of serenity, and quietness of a small town that is what you often see, it is pure and nice, like a wonderful picture, taken upon a tall place and viewing down to the wondrous beauty that it is.

I love the lights effects you made with this one, so peaceful so pure, I can almost feel myself being absorbed to the place where she is standing. The clouds and birds are well placed, not too much, not too little, it is indeed a piece of great work. My praise for this submission here. Faving it for sure.
