This is also a beutiful piece that incorporate a more complex composition, being slightly busier than your other pieces,
yet still retains a simple quality. I like that you also used black lines in this piece.
One element that I am uncertain about are the "almost" horizontal lines in the lower right corner. I wonder if
those lines would look better if they were actually horizontal. I think because they are slightly askew, they make me
just a little bit uncomfortable visually. That may of course be the effect you were going for ;-). But if it isn't,
then I think "straightening" them would make the piece easier on the eye :P.
Other than that, it's certainly one of the best pieces that you have done. I especially love the little cityscape,
which I loved in your other piece "Confusing What Is Real."
