This is the video reference I decided to use for the walk cycle animation and I also posted another two more as well.

Observing People Walking:
For this particular assignment; there were many different types of people that walk a certain way all being unique but also fall into categories. I noticed that people who walk in groups walk much slower because they're holding a conversation and do not want to rush the conversation. People who use the cell phone tend to go off to the side and walk around in circles until they finish their conversation and go back onto the sidewalk to head to their destination. I also noticed that older people tend to walk with a limp for the simple fact that it is much harder for them to walk because of their age. Business people and students walk much faster; they are always in a hurry especially in the mornings. During late afternoon, people tend to walk much slower, they're much more at ease when walking. Another category of people I noticed were the tourists; the tourist are usually walking slow and observing the area and always carry shopping bags. Despite of the categories, I saw a huge difference between men and women. When women walk they move their hips more. And for more "heavier" people they walk side to side with their legs more spread out.  Overall, I observed that even if people are just walking they seem to reflect their personality or mood at the time.
