which idea is better? be honest.?

I love the forest idea. Green is MY favorite color, too, but it has to be dark green. I do NOT like neon green. I had by current bedroom done in a dark green, too. It's VERY calming.

Waves might always reming you of the SOUND of waves, and that might get annoying.

Ooh green is my favorite color too! :D Lol I would pick the forest, but it depends on how you're going to paint it uk? If you were t do realistic waves then I would say no. if you were to do the cutesy wave designs then maybe yes.

I think maybe if you go for a dark forest green, it would be nice. Just remember that your room will be kinda darker then, even with the lights on if you have a light colored wall now.

You could try drawying in trees with large branches. Idk if you have a lot of stuff covering your walls, but if each wall was for each season, (spring, winter, fall, summer) that would be sooo awesome!! So you do forest inspired designs for that certain season. If you move your furniture around a lot, each season, you could move your bed to that side of the wall! That ould be a great feeling of change :)

Both are nice, plus you have to pick one that will suit your bedding and any other funiture you might have in your room (computer desk, chairs, carpet or rugs, etc.)

Bedrooms are a room to relax in so if green is a relaxing color to you, than I would go with that, although blue can be a kind of cool color, but I think green with go with more things.

Maybe if you have green walls and kind of tanny or brown stuff in your room it would look more foresty.

defintely the waves. It'll look prettier, especially if you make it light blue
