Here’s this year’s SketchUp 3d Basecamp Keynote video. If you have time, it might be worth it to watch the whole thing and see the 2016 SketchUp state of the union. In my opinion, the best part is at the 29 minute mark where you’ll see some great work by Alex Hogrefe of https://visualizingarchitecture.com/. It's mostly Photoshop workflows, and the end result is eye-catching. This kind of work doesn’t have to use SketchUp of course. It’s more a discussion of image quality and feeling. At the 56 minute mark there is an interesting section on feedback based on the types of images Alex posts online. It’s good insight you might consider for the images you make depending on who your audience is.
