Another go with Procreate
I think Procreate is going to generally be my painting app of choice on the iPad. It's not possible to do a video of the process like you can in Brushes. The final size of the image is very small for printing. The last issue is something I hope the software designers will be able to address in the future, but quite honestly it's a fantastic app for very little money and personally I find it much more usable than Brushes.
