The banner is garish, but that can be easily remedied.
Something I don't like about your art in general, however, is your positioning of text. Otherwise, you've become quite the artist. I don't mean to sound smug, but I really think that your designs would look a lot more professional or a lot more, fluid if you observed your spacing a lot more. For example, on your signature, the space to the right of
www.beywiki.com needs to be equal to the space on the bottom, the same can go for Beywiki on the top left.
But, I don't want to put you down, because that's not what you asked for.
So, fundamentally I just don't like the clashing of styles with the banner and the skin itself, the overshadowing presence of orange (which is a bit high energy for me) and a lack of synergy between the text font, the image fonts and the banner font. The globes are a bit of a hassle too, they're not compact enough and they just look too bold.
The last theme was a lot more unique IMO.
