Simple but a favorite. What does it need?

This one is a crowd-pleaser but seems to be lacking something:

I would start by cropping off some from the right and bottom to de-center the frog. - TF

agreed, after doing that maybe flip it horizontally. Some adjustments in a post processing program could be helpful as well.

Yep, Far to centered. I know it may be hard at times but getting eye level, lower would help as well. Live View is great for this if you are to old to crawl like me.LOL. Just try and avoid centering anything and learn to use the rule of thirds. It works, just google it.

I agree about it being too centered. Cropping the right which will put the frog to the right and will give the appearance of it looking into the picture.
Flipping horizontal might also help as western peoples natural eye movement is from left to right.

I think I'd actually take a bit off the bottom as well as the right, and maybe play with "curves" to try getting it to "pop" a bit more (lighting seems a bit flat)
