Here's a tail commission that I just finished up. The pattern was based off a reference the commissioner provided, and it is one of the more complex designs I've had specified for me to make. It was fun, and turned out pretty well.

Not all of the design is really visible in this photo, but it's got a yellow underbelly, yellow stripes leading down from the base and connecting together at a bar about 1/3 of the way down, and a yellow band encircling above a blue-detailed region at the tip of the tail.

Another photo of it

Oh right, if you'd like a tail like this, feel free to check out my tail commissioning guide ( http://www.furaffinity.net/journal/2485549/ ) and drop me a note!
