Creation of an icon

So I thought it might be interesting to break down how I come up with the icon designs.
I have to design 66 icons for use in this card game and have been looking at clip art, books and online image searches for ideas. Sometimes the idea for a card is obvious and I just sketch it up, ink it, scan it and start coloring it and adding effects.

Here are two examples where i "found" the idea. Its very obvious these inspired me to create the card image. The moon icon is very close to my finished design in many ways though there are differences in the face, shape, size of the star and the color "blue moon" So my question for the rest of you is, is my version a "steal' or is it 'inspired" by the jewely photo? I'd love to know what you think...

The other image is a little less obvious, but the photo of the 4 hands pointing in different directions obviously inspired me to create the confusion image. I wanted it to be a little more "creepy, so I added the eyes and the tentacles to create a sort of strange 'compass".

Its a real challenge coming up with 66 images, but I am making progress. I have about 10 done so far 9though not all have been approved by the games designers yet. Only 56 more to go...
