digital sketching

Some days ago, in the office where I work as designer, it happened to have few minutes free, so I did a quick sketch to keep my hands busy.

In the last times I think often about how to get new ideas and, as the final result, I try to realize so many projects in the same time that I can not really concentrate.
So now I ask to myself, do I need lighting in my head or there are already too many lights that I actually need to switch off some of them to see better what is in front of me?

That’s the sketch colored in digital.lampadine color web
