Some Recent Walls

[Bulf]

I started making these a few weeks ago, and I'd really really like some feedback on them. As @Serated said, they're all a little too similar. As it is, they're essentially the same with a different color, which'll get repetitive after a few seconds. If I make more in the future (and I probably will), what's a good way to switch it up and add more variety? Aside from using different colors/logos of course.

General cnc's are welcome too of course =D
