Does anyone know of a place where I can learn manipulations? I already know how to, but I want to improve my skills :)

Let me know.

Have you tried under Adobe Photoshop>Help?

Improvement comes with practice and trying different things. You can always undo whatever you don't like.

If you have some specific things you want to do, repost with specific questions, and we will try to help you.

I hope this helps. Thanks for asking.
