Matte painting is important and a good method to use in creating your anime backgrounds.  If you read alot of webtoons, manga and watch anime you notice often times the artists will trace over real life backgrounds for speed, accuracy and a nice look.  Look if it is good enough for the pros to do then it should be good enough for you to use.  Just saying.

I love 2d animation but for a one man show I think 3d is the way to go because once assets are built animation goes quite quickly.    Here are some great 3d animes that show you what can be done.

I’m okay using 3d to tell my story.

I saw this on CGBros Youtube page.  I always love to watch breakdowns of the anime process.    This one is a little violent for my taste but has a lot of good technical information.

I’ll just add another one.
