If I could offer one general criticism for your style, you should practice how to make your renders "blend" into the background rather than sort of popping out, there are plenty of tutorials out there that can help you with that. Otherwise I've noticed you have a thing for establishing a flowing colour scheme. This one could've been pretty good, but I think the background is too loud and demands more attention than the actual focus point. Also the round corners work.
I think you've got most of the pieces, now you've gotta try put them together more.
