Answer 1
"1. Post some of your favourite art of your fursona."
I don't have all that much of it, but:
1: New commission by @nventous, very cute.
2: Rather personally important drawing I did in April. Features @lizardsquid.
3: Many sketches by @shagoli of which I'll give an honorable mention to the sitting derpy one on the right.
4: I had room to upload one more and blushy bats are always good. :D (also self-drawn)
Answer 2
"2. Is this your first fursona? (if not, what was?)"
Sort of? It was the first one I'd call a fursona and I can't remember any good predecessor. The closest I can thing of was when i was very little I invented a character that was just a talking guinea pig (my favourite animal before bats) and he had everything I thought was cool.
When I was 5 or 6, "cool" apparently meant old cars shooting streamers and misremembered Chain Chomps (smaller, and the chain was gradually got larger)
