mm, great shot, I always have so much trouble capturing the water patterns, I can never get it quite right, well done, perfectly exposed...I know you requested advanced crit, but I really don't have any to give except that its maybe a bit noisy...need a noise reduction filter perhaps ;D
Beautiful photo. I love the blue tones. It could be a little brighter, or have a little more contrast, just to make it stand out more. Also, I feel the border could be slightly bigger; it will make it look more 'professional', however that's just my personal preference.
