I was lucky enough to win this art in a contest a fair bit back, probably about a year or two ago now, and at the time I was considering a Sergal fursona. When asked how I wanted the fur pattern, I told Ellie to surprise me with the fur coloring and I must say that even after this time I still greatly enjoy how the icon turned out. It is a personal favorite of mine and I'm still amazed at how well the bust was done and the resolution that Ellie did it in. The image here is scaled down to avoid any potential quality loss.
For a simple contest win, Ellie did amazing work, IMO. So, thank you Ellie for the wonderful piece.
