The story behind the banner design is short. Like what I have been saying on my blog, I am an illustrator than a designer. I enjoy doing both, but I love the illustration side more.
I did the banner design for a client. They have contacted me via email and described what they wanted. I know of Photoshop and graphic design, so I did it. After a few revisions, the client approved it.
If you want to commission me for design, feel free to contact me.
