When I started to create this image, I went through several different iterations before coming up with the one I decided to use. Here are the previous iterations that I wound up scrapping...
First Version
This was the first version that I created. One thing you'll notice is that the original one had an 8 bit character walking on the screen. It was actually an 8 bit avatar I made of myself years ago.
My 8 Bit Avatar (An Old Version)
I like to use it when I can, so I thought I'd use it for the banner image (I even gave it a beard this time!). I decided to remove it in the end because it was a bit too distracting when I mainly wanted to focus on the text. I still kept my original background though.
Second Version
This was the point I decided to add a box around the text, to give it a more retro feel, since most NES games at the time have a text box when dialogue appears. I also repositioned my character so that he was walking right in the middle of the path.
Third Version
I decided to shrink down the image, since there was just too much negative space when compared with the text box.
Fourth Version
At this point, I tried moving my character above the text, and changing some of the colors around so that there were less colors being used, thereby making the image look more like an NES game, since they tend to have limited colors due to the technology at the time.
Final Version
After shrinking the image some more and removing my character, I am now done with the banner image. I may still revise it down the line, but I do like how this turned out. Peace and take care! ✌
