40min Film Studies

So I've been doing this daily '40 min Film study' to increase my speed and improve my overall shape usage. I'm trying to be more decisive with the strokes. trying to get clean accurate edges to save me from having to clean them up later on which wastes so much time! also trying to hold back from doing details till the last 5-10mins. This is proving to be quite difficult tho :/ The time limit really highlights areas I need to work on, and to think before commiting to a stroke. I'm still colour picking which I would like to stop doing when I get a bit better the accuracy/proportions of my shapes. Here they are in chronological order.
