For inspiration, browsing tumblr / we heart it, usualy helps me ^^ some nice music too <3
As far as style goes, try new things! Browse tuts on deviantart/youtube, you will find yourself trying millions of different stuff, and at some point you will develop your own style as you go
But always remember, you should be the one pleased with what you create, so aim for your own satisfaction.
Hope it helps you somehow o/
And GL ^^
