Analysis of the designs.
Design: Mobile Application.
Cons:
Learnability: it's difficult to understand how to get feedback about your drawing from the system. User may not be able to understand that he should make photo after he drew the picture. Also there is no feedback from the system on your actions.
Safety: no possibility of cancel actions or making undo. If user made a mistake he won't be able to correct it.
Design: for children.
Pros:
Learnability: interface is created for "learn-by-doing". Every page contains one/two buttons and describes steps very graphically. Users receive feedback on every action through the words of the rabbit-artist. Moreover, some pages use metaphorical constraints like pencil or aquaria paint which helps user to understand if they choose pencil - they'll draw with pencil.
