My icon is my fursona so its both me and a character I created. Bramble Berry is like a slightly idealized version of myself as a cute squirrel person. He's a character that I have a deep personal connection and attachment to. I use him to represent myself online across all my art accounts including here on Tapas. Its like having a very well developed personal mascot. Way more people know me as a grey and purple squirrel than the number of people who know me as a human lol.
I make furry (anthropomorphic animal) art and this includes my comic. So using him on here just makes sense. He hasn't had a cameo in the comic or anything yet (one day!) but in my head I want to show him up in his treehouse hard at work making scribbles for comics in a Q&A down the road sometime.
