To be honest, there's no real emotion, interest or connection in this image for me, it's more of a snap really...
There is a great series of articles here: http://www.outdoorsphotography.co.uk/composition-1-the-kiss-technique/ by a chap called Ian Bramham specifically on composition. They're well worth a read! Hope they help
I like it. Maybe the composition is a little muddy as the kite is overlapping the cloud but overall I think it works. Any other photos or crops of the same sort? I would also say the kite itself looks a tad underexposed. Maybe bring out some of the detail.
