My grandson and dog
The 2nd one doesnt make sense, older boy in what looks like a kiddie play area?.
Work on the cropping, maybe add some vignetteing, and bounce the flash a bit more, Not sure if you have a fill or 2nd one to practice with..
top pic, I feel would look way better if he had chin up maybe looking over instead of up?
Just throwing that out there.....
This took me about 5 minutes........
Hope you dont mind..
