I'm new to the PO community, and I just made this theme last night. Could you guys please judge it? I need opinions how to fix everything that is bad.
Eh... For starters, you might wanna fix the images for the Old Battle window as they don't fit properly. You can download them from this thread: Spoiler Battle Fields Also, try to have some transparency in your theme as the solid white covers a lot of the Team Builder. You might wanna use better images too. Overall, you have a great idea but try to be more creative with it all around.
Often a way to help with images is to choose super large images. So when image searching in something like google only filter in large images. This means the images will either be to size, or they will not pixellate and lose definition when you enlarge them (slightly). This makes for a crisper, more professional feel to your thememaking. As a clue on trying to phase out a little of the white, try using some of the green you have through the theme?
