Hi. This is my first post on this forum so hello everyone : ).

For a couple of months I try to make pixel art so I'm still a beginner obviously.
Today for the first time I tried to do background.
Below you can see what came out(if it is not uploaded properly, sorry for that, but like I said, I'm new here). I think it is not so horrible, but I want to ask you, what do you think about it.
If you think something is wrong with it please tell me.
