I honestly love it when a client is happy with my work because that means I did something right. Often, as an artist or designer, we don't always completely understand what the client has communicated to us. Sometimes, we think we understand but later, we find how wrong we were.
This was one of those times when I had a good working relationship with the client. I had already done many sliding billboards, 300x250 banners, and 728x90 banners throughout spring and summer for the advertiser so I knew what he liked which gave me an advantage.
