Skipped week 5, could not complete the homework. Week 6 was about putting everything together and try to push the sketches to the finish. I have to say I am always very reluctant to do that, since I dont have fundamentals solid enough and rendering a weak drawing is like putting lipstick on a pig. But here you go, I did again a series on live cows.
These cows are a bit weird looking, but if you compare with my first attempts long time ago (for dynamic sketching 2), it's still a progress.
*update* here is a screenshot from the video feedback from Jon, the instructor. I really like how he pointed out the missing planes on the cow face..
