Wow.. I feel honored someone would take my doodle as inspiration. I know nothing abut Vue or it's capabilities. If you look at the link in my signature, I create a tutorial for GIMP and using both video and text showed how I made it by using Layer Masks in GIMP. One thing that I think really helps make my tutorial come alive is the shadows in the depth of the creek as well as the water going from solid to none as a gradient to simulate a shallow transition bank.
Anyway, nice work!
