For my original idea of remaking an opening credit sequence, I was going to go through a city for the opening, however, I had no idea how to do that. After searching for a couple of tutorials I came across this one and I thought it did an incredible job of teaching you. It was extremely easy to follow along and for that I was grateful. I went on to watch a couple more of his videos and I thought they were really interesting and I learned a lot. I would definitely recommend watching some of his tutorials to help you out. He covers a lot, from basic techniques to more complex, but he does it in a really easy to follow sort of way.
