A quick doodle I did yesterday in uni ‒ well, to be more exact, in its stairwell, placed outside the building. It's truly a lovely (and frighteningly high as hell) place, with an amazing vista of São Paulo city.
The sketch was done in A3 paper with 6B pencil. I know there're a LOT of mistakes but I couldn't help but scan the image and mess with the colors in Photoshop.
I hope you like it, though!
