The small fountain appears to be tilting towards us because the ellipses are too open. See this link for tips about ellipses in perspective: https://www.youtube.com/watch?v=xMRhuUQREMQ

I'm so glad you took advantage of the 3D aspect to rotate the images and animate them! That's the whole idea behind the contest using Pixelsquid, nicely done!

Your sources are all okay but source 5 is the download link, always use a link that shows the usage terms/license as well as the image. For this source the correct link is https://www.pexels.com/photo/sky-earth-galaxy-universe-2422/

Beautiful image very well done!

Congrats Angel!!

Logically speaking I don't see how these elements would fold up when the book is closed. The parts in a pop up book are usually 2D images that stand up when the book is opened to create the illusion of a 3D image and fold up again when the book is closed. You show 3D images which don't look like they could fold up flat.

Congrats!!

As CMYK46 mentioned source 4 has been highly manipulated making it a CG render and not acceptable as source. We do allow images with minor adjustments such as those made to NASA and Hubble images but this has been reworked extensively and can't be allowed.

To answer your question, no, wallpaper images cannot be used at all. These are usually altered by their authors and they do not provide information to identify the original source(s). All source images must show ownership/license and/or usage terms for the image(s). You can find information on acceptable sources here: http://www.pxleyes.com/forum/viewtopic.php?f=5&t=5644 and also in the Beginners Guide found here: http://www.pxleyes.com/courses/guide/

Very nice image! Could you show the source for the water or if you created it please show how in an SBS. I'm sure the Contest Moderator will be asking so you should show that before you're sent a warning.

Looks like you worked on the globe some more, much improved IMO!

Lovely work indeed!

The perspective of the table is still way off. Perspective isn't that difficult to learn, there are many tutorials you can find on line about perspective.
Here are a couple from youtube that are very basic: https://www.youtube.com/watch?v=rgeMDL-gXDQ
and this one about cylinders: https://www.youtube.com/watch?v=xMRhuUQREMQ

I agree with Bob, instantly recognizable as the well known story! Love how the sneakers make this a modern version of the classic!
