This is my first Bob Ross painting. I had issues with the waterfall, and I didn't blend the bottom of the mountain enough. I also think the clouds are a little wonky. Lastly I was too aggressive with my water reflection in the center -- I covered up the white area that I needed for the sunbeam reflection down the middle of the water. I was happy with my tree trunk, though. Overall there were some issues but it was my first painting (of any kind) so I am fairly happy with how it turned out!
