Links need to lead to the actual photo used. Check your proportions...the head is too small.

CMYK46 is right about the links.
For the lion use this link: https://pixabay.com/en/lion-lion-s-mane-cat-big-cat-989140/
For the background use this link: https://pixabay.com/en/girl-beauty-model-pretty-outside-1128523/

Be sure to change them in your entry. Remember to use the correct links in the future, links must show the image used and the usage terms for that image.

Great Idea author, a little hint on matching the face size to the body, when resizing the facial features turn down the lion/face layer opacity so you can align the eyes so the body matches up to the size of the head then return the opacity to normal. This will help balance the idea. Also using a Lioness Face instead of a Male Lion might help bring the image into a more balanced realm. (And eliminate the torture of the mane)
Also matching up the texture of the body with the texture of the face to create continuity would be beneficial.
I can see the work you did in the body and that's a great start, getting the face to match the feel would help in making it look less "Cut and Paste."
You still have plenty of time to fix the image for improvement.
Good luck and welcome to PXLeyes.
