Looks good, I've some tips for you so you can improve your skills.
Background
There is some noise added on the background, delete that and change it to black or a darkish gray.
Logo text
I see at the top of the design on the left some text, I think is the server title and slogan.
Make it bigger and add it in the middle of the header. The slogan may stay smaller then the title.
Boxes
Make the boxes a little bigger, I mean those boxes:

Font
Use another font, you can use it as body text but not for the menu or head text.
Also for the logo give it some effect.
Custom text
The text "You must have our custom patch to play" need a box to.
Add a red box with some effect on it and change the text color to white or light gray.
Those are some option which I should change. It's up to you if you want to change it.
