I have been playing with the size of paintings and levels of detail. The image on the bottom is huge and when complete very detailed. The second one is a bit loos and much smaller where the first is a bit of a happy mix of detail and smaller size. The two smaller where nice projects that could easily be done on my desk. The large one has taken quite a bit of time and has needed to be done mostly vertical. They are all acrylic but the larger one is on illustration board.
