Tons Of Sketches

I made this sketches to practice composition and efficiency in ideation.
i started on january the 11th, and always recorded the process, i worked for about 15 to 50 minutes each day on them, as either a warmup or before going to bed. it was fun, and gave me a good idea on how i do use brushes, how i group values especially when i only use 2 values (black and white) and where i do spend a lot of time that could be used better elsewhere in this stage.
