Throughout my travels I've been taking pictures of my friends sleeping and editing them using the WhatsApp pencil to create a comic strip. This has worked really well, and I even made a stylus out a pen, a cue tip and some foil. However I feel I've reached the limit of what the WhatsApp pencil can offer me. Can anyone recommend a simple doodling app that will let me import a photo and then draw over it. Ideally I'd want the ability to have layers and and to cut and paste. Obviously an assortment of brushes would be fun too.

I have the app sketchbook, but it's a little too advanced for my needs and frustratingly also lacks some very simple features (such as deleting/copying selections).

Thank you comrades.
