Its funny how you change over time. Which includes your fursonas' designs. The one on the right was m old fursona when I was younger, the colors were a bit more harsh and the design was somewhat simple. The one on the left if my newest fursona (2-3yrs old) with a bit of a complex design, yet trying to remain within natural-looking tones of brown. I'm sure there will be tweaks later on, but I just thought this was fun.
Enjoy.
