This caught my eye because it was such a pretty photo. I think the colors are great and it exhibits excellent composition. I also love the depth of field, it gives this photo a very soft feel.
My biggest gripe about this photo is the lack of originality since many photos like this have been taken before. To be honest, with photos like these, I think there's a limit to how original you can be, but I would suggest playing around with the angle and seeing what you can come up with. This is something slight, but my only other bother is the bits of yellow we can see in the background. I think lowering their saturation so that they're not as visible would be more pleasing to the eye.
