Ok ,
Ron, remember your dog carving. There is nothing flat on an animal. I think I ill make you a few acorns to carve. I think the canoe looks pretty good but I have an advantage on this on , I saw it in process. I think it is still just a bit forward, which is causing the shadow between the buck and the boat to be a bit heavy , since now your playing with something you can't feel , I will do my best to describe the issue.
The buck is only slightly in front of the bow of the boat. Because we had to go deep to remove the knot that shadow is falling behind the boat edge instead of in front of it as it should to show the buck is forward.
As it is now , it looks like another step the buck will be in the boat. Your trick will be to move the front of the boat without distorting the image. There is plenty of wood there to move it in , but when you do you will change a lot more than just the canoe to buck perspective.
The flow lines Susan suggest is a great idea it will highlight the water but if you add the water ripple there make sure you add it to the bucks legs as he is standing the water as well and the current would give a little ring effect at the legs.
Now I will go back to my hole
