I animated a diagram for a video project I’m working on but have used graphics provided by the client. I think they are slightly outdated and would like to modernize them. I was in a graphics design high school so I am familiar with illustrator and all that it takes to make graphics, I just want some pointers in regards to what is trending now. I feel like rounded edges are too old. I’m also guessing that flat designs with little to no shadows are still in vogue in 2020. What should I use as reference?
