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.

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

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

The source for the nude no longer goes to the image but to a search. As the contest is in vote only mode, pleas add the correct link in a comment.

spider has no one to love hehehe good luck author

Watch your erasing tool on the skater's left elbow (the red one).. it's very choppy (I do it all the time when I don't have the magnification set high enough). I'm only mentioning it because the source photo has such a nice elbow that has disappeared. No big whoop.. I really enjoy the motion feel, I want to get my toes out of the way
It may not matter due to the "Blur" effect you added, but it kind of feels like his elbow and part of his butt are missing and not traveling.. but what do I know? hehe.. great Idea and nice finish. Good Luck author
