I like the photo, but I dont think it represenst authority. Let me sugest using a bigger photo in the challenges, if the file is too big to enter try decreasing the quality of the phot to 8 or 9 you will never notice the difference with you eye. But it makes the file alot smaller and alows you to upload a larger picture.
I wish this image were bigger so I could see it more clearly. I got great advice from another person on my last challenge. Make one side at least 640 and then go down from there until you get under 150 pixels total. Great use of light and color. I wish I could make out the girl's expression.
A bigger photo would improve this. Try to use all 640 pixels available to you if your cameral will allow. This small and it's hard to see the fine details that would boost the score.
this is a cute snapshot, but not really an image that represents authority. also, in the future, you might want to increase the size of your submissions (you can go as long as 640 pixels on the longest side).
