#2 and #4 are the winners for me!
I just wish we could see her mouth on #2...that would complete the picture and show us her determination to make that throw. Great job of getting down to shoot at her level.
#4. Also a great job of getting down to his level. I think the look is of "expectation". Is someone throwing a ball to him? He looks like he's about to catch something and he's engaged and happy about it.
Neither #2 nor #4 has the model looking at the camera...usually a way to engage the viewer...but, in this case, it appears the kids are engaged in something else.
I like them. Thank you for sharing your work. Welcome to POTN!
