And, actually, there's a fairly good reason for that.
But each app does have a flavour. Images made in Adobe Ideas will always be completely different to pictures painted in Talkboard. ArtRage has a completely different output to Sketch and so on.
If I'm learning a new app, often with people looking over my shoulder, asking what I think, I like to give as little concentration to what I'm drawing so I can talk and learn and explore as much as possible. That means that I generally draw a Frog, a Squid, a Marmite jar or a Snail. Secretly (don't tell the others) I think the Snail might be my favourite.
The other reason I love drawing snails is that, when I teach, the snail is a relatively simple process to teach people how to draw on a screen. Which always makes me smile, slime is not an obvious subject to paint onto glass (and for an extra stretch task bonus there's a healthy dose of Fibonacci in there too).
Very hopeful there will be some exciting snail news soon. The optimistic dreamer in me has an eye on a snail project that would be utterly wonderful to be a part of.
