Since i shutting down my blog and move entirely here,
i just make a quick update on my banner AGAIN! Yes this is the fourth time. i just like to design just to fill in my time.
just follow the color depending what mode are you using it. if you are using night mode, you should follow the upper color and bottom color. so the illusion will works. it looks like your banner is one with your menu bar and it will looks cleaner.
If you like to try your self, make sure you use photoshop, because i only have psd files. Hope this will help you! You can Download here
