Okay, so I've luckily got another bout of inspiration to work on my game, and have returned to it. Thing is, some of the backgrounds look pretty, well, bad. I've been trying to update them to look slightly better, while still retaining their simplistic style, but I've been having a lot of trouble. Especially with this background:

Now for the outside of the school (Which will only be seen in cutscenes), I know I need to do something with the grass and tree. The flag will be animated (And probably redrawn too), and I need to make the sky les... Plain. Any help with any of these would be appreciated, as I'm completely stuck now.
