Anna, I'm guessing this is a web site you're responsible for? If so, I'd recommend revising the copy on this site. The first sentence reads: "Animated Desktop Wallpaper is not a widely-known product which provides a qualitatively new substitution for usual Windows wallpapers." Why say that it is not a widely known product? This implies it is unpopular and things are usually unpopular for a reason
Anyway, I'd revise it to say something like: "Animated Desktop Wallpaper is a new product which provides an exciting substitution for boring desktop wallpaper on Windows."
Next paragraph: "In addition, almost all Animated Desktop Wallpapers feature interactive functions and 3D - images, such as, for example, a butterfly that starts flying when you point at her." "Such as" and "for example" are redundant. I'd re-order the sentences in this paragraph to read:
Interactiveness and dimension are features of Animated Desktop Wallpapers. Life flows naturally, e.g. a butterfly that starts flying when you point at it, dawn sets in after night passes and dusk replaces day-- nature changes on your desktop.
I'd recommend having a copy editor take a look at this web site, especially considering that this is a site intended to make sales. -Matt
