This was indeed a challenge. I like working with the knife but I am no wizard with it. The end result is rather poorly but I think it also had to do with using a square budget canvasboard (10"x10") and the cheapest oils ever (2 USD for 12 colours!). The latter was perfect for spilling a lot of paint yet showed poor results on canvas. Those cheap oils also didn't blend very well. In total, this creation took 45 minutes to do.
It is yet another experience and will happily move on to the next one!
