Of course, here's the .tgd.
If anyone wants to render it bigger for me I'd be really grateful, 600x450 - 0.6 detail is as big as I dare with all these ray traced reflections and my unstable pc(it will shut down without warning if I push it too hard, I think I have a power supply problem).
You'll see, if you render it, the postworked areas, namely the top-limits of the puddles on the ground surface, which has been blurred as they had too sharp a displacement-clamping line, and some real reflection problems at the lower portion of the ground, which I've fixed after rendering.
