Keep practicing, never give up!

I can see that you are settling down for a particular style, but you should definitely play around with your stock more - Most of the pictures you use in your tags seemed to be stretched. Also, Try using brushes and vectors apart from just filters.
I also encourage you to visit other forums and just look at their tags. More often than not, each forum has its style/fad.
