To Cendres
If you have the Knockout program, why not go to the Corel newsgroup.
Describe the work and the problems you have and
i'm sure you'll get feedback, even if you are using Photoshop.
As always, good result comes with experience. But if you have
very complicated pictures, you can't avoid some cleanup or
adjustment work afterwards.

By the way, Corel is coming with a new Knockout
version 2.0 soon. But its a pretty expensive upgrade
i've heard.
