A cutie.
You can get rid of the dark line on top of the dandelion by using the dodge brush set to dodge shadows or you could use the "blend if" option.

Cute little thing... look at his eyes..

Made me smile for sure 😂

It's amusing for sure, but the teeth appear to be stuck on the bottom lip instead of protruding from under the top lip. A bit of tweeking needed in that area.

Well... it made me smile too..... !!!

Boy's face is too light. Also the man's body has an "HDR Look" to it, so maybe try to match the boy's face to the body. The boy's face is too "soft" for the body.
