Ah, that's come up very well - does Procreate have a stabilizer option for when you're inking? I just ask, as the lines seem to end with a nice crisp point.

I'm soon to acquire an iPad to use at work, so I'm curious as well, does either Procreate or Sketchbook Pro allow you to manipulate an image after you've drawn it? I wouldn't be looking to do anything fancy, but I like to squash and stretch sketches in photoshop with the transform tools and it'd be handy if any of the portable apps supported that sort of thing.
