Sketching in colorful pens

While it was not a great day in the US financial markets, I enjoyed a great day in the studio.
I experimented with the idea of creating my sketchbook canvases without the grid that I was outlining to mimic an old fashion notepad or a sketchbook.
I decided to give it a try and if I still missed the grid, I could always add it in later.
But the sketching took a new direction and I ended up really enjoying sketching in colorful pens.
I left a lot of white space around the images.
I thought that it works better to intensify the power of the simple lines.
I will post some photos tomorrow and elaborate a bit more about it.
