From an ex-Springfieldian - I do miss Washington Park. Looks like you have a good model. Don't worry too much about scores and comments on dpchallenge - it can be pretty hard for newcomers.
The child in the foreground seems blurry. Try using a higher shutterspeed when taking these photos even in low light you can force it using manual setting.
Good idea, but I wish it was in focus. Seems that the lighting may have made it difficult to get a quicker shutter speed considering that the little girl probably wasn't interested in standing still. I like the idea of having her in the foreground though.
