I'm new to DA but I wanted to say that the light refraction in the water was what I was looking for (I was reading some reference recently about the classic tube in the glass effect) but apart from that I've got no complaints, fantastic vivid colours there Erik.
I like the vivid colors that you used which is ironic because i'm not a big fan of green,you did forget to "bend" the water but people's attention is easily distracted from that minor thing by the radiance of the picture
