The first and second version are just different treatments of the carp color and outlining. The bottom one shows what happens when you use a .png format and stupid blogger gives it a grey background that I can't figure out how to change for some reason. Pretty cool looking actually.
Special thanks to Chris Galvin who pointed me in the right direction for grabbing the correct software to make a smoothed and scale able design in vector format. I used IncScape which is freeware and really quite easy for a relatively simple project such as this. One thousand percent better than a) drawing software on my phone that I started with and b) Microsoft Paint.
