Drawing Proportions

Unintuitive to use

This app is invaluable for the professional portrait artist. First, it lets you know exactly what you need to fix - saving you an untold amount of time and consternation. Secondly, it surely is a way to impress your customer when you show them their reference photo or sitting snapshot morphing into a finished painting or drawing! Anyone who has ever done a portrait commission knows that people's view of their own image can often differ significantly from reality.

It makes it useless if I am not able to adjust the sizing of the two images and parts that line up to each other. The app lines it up for you which means redrawing the entire picture.
