It's a nice work, congrats on your first wallpaper! I like the colors in the background, but I'd go for lighter outlines for this - maybe a dark brown or gray. Black is too contrasting against the brighter colors.
In the future, don't forget to add your signature to the wall, it's important. And you should also write a bit
more about your work - for example:
- how long it took you to make it;
- what resources you used (scans, brushes etc. - make sure to link to them too!);
- what were the most difficult/easiest/(least) favorite parts;
- what did you learn making it;
and anything else you can think of.
