Hi - I see that you are new to dA so I will *try* to be nice.
It is NOT acceptable to use others' work and not credit them, especially if you have used someone else's artwork and NOT asked for permission first (which I seriously doubt you have, especially since you left the original watermarks on half the images).
Also, your work (not that I would even consider it "yours") belongs in the category of "Digital art >> Photomanipulation".
Not "Photography>>People and Portraits>>Glamour".
If you didn't take the photo, don't act like you did and submit it under the photography category.
Please correct this, and PLEASE stop using stolen artwork. It's called copyright infringement and it's illegal, not to mention morally reprehensible. Someone worked hard to create the images that you have stolen. This behavior is only going to get you kicked off the site and piss off a bunch of legitimate artists.
It's ok to appreciate the art here - that's what the "Favorites" and "Collections" applications are for. It's NOT ok to take someone else's artwork and pass it off as your own!
