I recently drew this portrait in Artstudio Pro, and I should have been able to do it 100% in the app, but the lack of "use all layers" when doing smudging/blending forced me to have to export it to desktop Photoshop for the final portion.
It would be nice if we can get that feature, so when using smudge/blend brushes on a layer, it will interact with all the visible layers. This will allow us to keep the foreground layer separate from the background, but still be able to have them interact with painting.
