This App creates the most professional results in converting photo's into drawings of any App I tried in the App store. The results are actually quite convincing as watercolor paintings.
The options the App offers seem a bit limited (choice of colors, effect, mask) but once you get the hang of it there are sufficient options to create great results.
The results are really creative, and this feeliing of creative power clashes a bit with the lack of manual options. Watching those water colors emerge you really want to get in there with a manual brush and add some color highlights in the otherwise duo-toned image. I hope the developer will continue to work on this App because it could easily become a powerful and important creative tool for designers and creatives alike.
