Struggle bus

I'm playing with the Paper app by 53, and I'm using the Pencil stylus.  I'll admit that it is pretty fun, but it lacks a lot of things that I would think very important in a digital sketching app.  You can't color pick, and there are no layers.  You also cannot import pic or photos.

 The Pencil stylus is buggy for me at the moment.  Sometimes I will be painting, and all of the sudden it will smudge or it will erase.

Anyway I did this sketch of a bus.  I named it struggle bus because, well struggling.  

I will keep trying this app out, but I may return it before the 30 days and save for a stylus that offers pressure sensitivity.  We will see...
