The text need to be changed. You could probably keep the font, but the positioning is kinda bad. I would just place the text somewhere else and make it smaller and leave that white space. Colors are nice, but in my opinion some round shapes would look cooler. Like, more playful.

I'm glad that my work has inspired you! I'm deeply in love with the pen tool, so I guess you will be seeing some more stuff later on. I hope you will post more vector stuff too. I got inspired by a professional swedish designer that is a member on another forum I often go to, and I spoke to her and she comments my stuff and so on. She is AWSOME in vector art.
