Hi Jen,
This is looking really cool - the waterwheel is awesome!
I don't think you quite understood what I was getting at. (Sorry, I thought it was a jetty before you put the detail in)
The axle appears to come out of the building, over the grass and then under the water/grass join. I can't make this make sense however I look at it.
Also, to make more work for you, if you haven't noticed it yet, you haven't put any shadows on your fort or the old wall sections yet...
It's looking awesome, come on you've got a couple of days left, you can do it!!!
