What are some ideas of what pictures to paint on my walls of my bedroom?

I was thinking about painting this on my bedroom wall but just haven't gotten around to doing it yet. It is the Redwood Forest. That is very simple to paint and hard to make a mistake on as any mistake looks like it's supposed to be there. If you want to look at what they look like you can on the computer. Just type in California's Redwood Forest. I used to live there a long time ago. The Redwoods make a beautiful mural in any setting.

If you are whatever like most mural artists, you'd as an alternative not have your own work as close to you as on your own bedroom wall! Why now not ' play- trustworthy' and create a massive montage of cuttings from magazines, leaflets, and many others and many others, perhaps with a theme, like ' My favourite matters' or ' prior, present, future', then that you may add or subtract or quilt items on the speed of a glue- stick! Do not forget to take photographs of the finished masterpiece to hold on your grand- youngsters! LOL

I'd say take this question to a DIY forum or artistic forum and you'll get better answers. We're wrench-heads here.
