Warping in Photoshop CS3? Help?

Question: Warping in Photoshop CS3!? Help!?

I am getting in to photo editing and digital makeup alot!. I just got PS CS3 and I can not for the life of me figure out how to warp only certain parts of an image!. I have seen video tutorials where they warp eyeshadow brushes to fit certain eyes(this is what I am really interested in)!. This is what I am talking about(here someone is warping teeth): http://i159!.photobucket!.com/albums/t126/!.!.!.
How do I do this!? I can't figure it out!

You just have to use the marquee tool to select the area you want to focus on before you choose edit->transform->warp!. Hit enter when you're done and it will go back to being a selection!.Www@QuestionHome@Com

Go to Filter, Liquify!. Thats not what he's using in the picture but it works as good!. All you have to do is take your time with this tool and it will look great!.Www@QuestionHome@Com
