This was all done on the iPad, the first try to do a colour drawing all on the device. It was not all done in one app, however. I started in Procreate but had to move over to Affinity Photo to do the doing and burning of the greyscale sections before colourizing them for the final look. Procreate can't do that. There was a lag with the Apple pencil as I went along, some of that was an Affinity update in the middle of the drawing process and seems to have worked itself out after a day. It gave me a good excuse to get into the very different interface on the iPad version of Photo and I have much better grasp of it now.
This was maybe not the most exciting of my acrobat drawings but beggars can't be choosers and there were no free shows for me to get new references from this year.
