At this point my scribbles are pretty lame and obvious but here's the cool part: it does the work. These lines challenge your grey cells like nothing more and you try your way around it trying to be as less obvious as you possibly can. But the obvious just comes out, and it's ok.
It's ok because it's still a learning period . It's ok because the grey cells are not as flexible as they should be. It's ok because this is something new.
I am so glad that I was tipped about this app, and since i installed it on my phone I can now do these challenges everywhere, If I don't forget my tiny A6 sketch book, of course :).
