Maximus, with a pic of smoke with a black background, if you import it as an adjustment layer in Screen mode, the black disappears.

looks good. How did you get the black background out of your smoke so that it was transparent? Nice effect.

Good luck author, fun use of the source (I'm waiting for the Hulk to break through) hehehe

EDIT: New sources are useable.

Please post your source links, and read http://www.pxleyes.com/guidelines/photoshop/
Illustrations are not useable sources. 5.6. 3D Renders or Illustrations as Source:
Using other people's 3D renders or illustrations (even with permission and no matter in which form they are offered) creates a false impression of your artwork. So 3D renders or illustrations can not be used as sources, unless they are entirely created by yourself. Only acceptable non-illustration brushes and clip art may be used, but you need to mention them as a source too. Don't use an image that has been altered by the source owner nor an entire work created by someone else.
