It's nice! 🙂 The music is a nice back-drop, and the kids are definitely cute, and well filmed. They seemed very much at ease with you when you were filming them. 🙂 And, of course, it tells a story I agree with whole-heartedly. 😉
The only major thing I'd suggest is that, if you were actually running this in a place like Texas, it would be a little irresponsible to do this PSA with only white kids. They make the point that kids are all the same inside and all deserving of love. But you've chosen to only focus on one portion of your local population.
Some minor things that I would suggest... you might fade in the music a little more gradually in the beginning. When you dip to black at the end, you might put up some text. The voices were a little difficult to understand, and in particular the announcer's (your's?). I was with you till the end, and then I think you said, "Let them know you care." But I wasn't completely sure. You could probably do things audio-wise to make this more understandable, but flashing up a simple slogan at the end would work too. I don't know what your time constraints were, but the whole PSA was just a little on the fast side. It felt like it was running along ahead of itself just a tad. I think if it were stretched by a couple of seconds it would seem to be paced just right.
