Great job with the trunk author awesome improvement

CMYK46 is right, you should correct the links as he explained. The box marked "text" is for the description of the image and/or attribution. The pixabay images don't require attribution so use the text box for the description, for example source 2 type in "white tiger".

It's best you make the changes so members can find the images by clicking on the source rather than having to copy/paste to see the images.

Author, a little more effort into the "Out of Bounds" theme might help in this design. As it stands, it seems the lioness on the top left is the only item that is out of bounds. I do like the fade from wall to forest in the background. (I'm sure that is Out of Bounds as well, just more subtle.)

To improve your entry, you might want to have the Elephant "stepping out" of the painting as well. The cut off rump of the white tiger is screaming for a frame (another out of bounds effect easily added)repeating the same Idea with the gorilla as well.
...
I do like the idea and the composition is well done. Just giving you a little heads up on improvements... for what it's worth. Good luck.

Author, you're placing source links in the area used for text. Use the other box.
