What is the medium that you are working in, it's always a great thing to experiment with your work. Whatever it is to try new things or just creating things offline, these things are part of your journey as someone from this industry.
Gleb Kuznetsov is a Russian designer that comes up with pretty gorgeous UI pieces for apps and web. He's got a pretty awesome portfolio with many great examples of how beautiful an interface can be. Check it out!
Here you can see a brief selection of his work. I really enjoy his approach on graphs, using gradients and glowing effects, which brings a "Tron feel" to it. For more of Gleb's work, please visit his portfolio at Dribbble! I hope you enjoy these as much as I did. Cheers! ;)
