Sketchy lectures

Currently feeling sleepy but must drop this or it'll just be another work of mine that got nowhere beyond by books.
I was bored of straining my ears just to hear what was being spoken and decided to draw from what's in front of me.
I couldn't draw too much desk and choose to focus on the one in front of mine. I also didn't go much into the details of everything and jut did what I felt free to draw in 2point perspective
