Wet on wet (on wet!)

On a cold winter Saturday morning, I went down to the American River to practice some wet-on-wet techniques. The sky was more of a dark grey, and the trees were probably not as green as the color I picked, but I was just laying some background color in to represent the far bank of the river. The near bank was just mud and grass so I started with laying down brown and some green highlights.

At this point, I've been wetting just the area of paper that I'm going to color and then laying in the color, moving it around to cover the space, tilting my pad slightly to allow gravity to help. I tried to keep a thin area of dry paper between each section to keep it all from bleeding together (had some trouble with that on the far left). 

And then it started to rain! So my very wet paper started to get even more wet, but each raindrop was creating a nice effect on my painting. (I wonder if I could recreate the effect in a controled environment?)  At some point though, I had to cover it for fear of complete destruction of the peice, but in the process of trying to protect it from the rain I touched the wet paper causing blemishes on the left side.

So the question that I have now: Where do I go from here? Add in details- trees, reeds -to cover the blemishes and finish the scene I started? Or, as I look at this scene now, I'm more reminded of a starry night on Lake Tahoe.  Or just paint the Golden Gate Bridge and make the foreground San Francisco and the background Marin County. What do you think?
