Bit late with this prompt of flow. It was posted on Tuesday but I missed it. I drew two lines in curves by holding a blue and a green felt pen together to give me a meandering river shape with vertical banks, the used blue, green and turquoise colours to give an idea of flowing water.
Or is it turquoise? Drawn in ArtRage oils. Finger painting on my phone. One of the challenges with drawing on a phone is if you don’t use a stylus (I can’t find mine) and the tools on this app means the colours smear together. I do have ArtRage on my tablet. That’s the pro version with many more tools but my phone is easier to use as it’s not as heavy on my arm.
