This Does Not Let Me Sleep

I’ve just got up ( a little bit late since I went to bed at around 4 last night) and feel this urge to draw everything around in the back of my head and at the ends of my eyelashes. I was just having a glass of water in the kitchen and saw a new flower on the wildrose-bush outside the window and the first thought I had was how would I draw it, which no of the liner to use and how the final black pen lines would look on greyish paper.
