The background is very simple, I only add some blue light and logo to it! I really can't make up my mind to add what!
The most difficult part to me is the line and color. This is the first time I use the brush to color (usually I use pen tool).
The wallpaper is not finished yet, there are also some where to be modified,so I really hope you can give your comment, that will be very useful and I can modify the picture, Maybe this is the last one I made this year, because I'll having test in the folling days, so I want to made a good end to this year's wallpaper work.
Thank you!
