I enjoyed working with this application although it took quite a bit of time to work out how to utilize the different tools. It was also a challenge getting the images to still look like what I had drawn once Scribbler began. Using a mouse to draw is also very difficult as I am a bit of a perfectionist and wanted perfect circles when that was not going to happen. I added 3 images because I couldn't decide which ones I liked best.
I did not like this program at all. I actually found it more difficult to work with than the older edition of scribbler. I am not very fond of the connectivity of the lines. It made it nearly impossible to draw details. After a lot of experimenting I did find ways around that but ultimately, this is not a program I would use again.
My first picture was copied over a sunset scene. I tried to mix the different shades of orange, yellows and reds to make a smooth background. The second was a free sketch of dancing feet.
This final image was my attempt at a screen shot while experimenting with the extras you posted. I kept trying to get a good shot but by the time I would get the image captured, most of it had faded.
