Yes I have been working on these sprites for a while (the WIP sheet is in my scraps & constantly being updated).
Sheet still a WIP. Still need to add the different views & poses. Now working on the side view (hoping to edit it soon) & ball-rolling animations. (Also note that I'm updating the sprite's look from feedback & to make it much better)
Emotion expressions now added. Will make different mouth expressions later.
You may:
1.) Contribute (after asking permission). 2.) Add more to the sheet (after asking permission). 3.) Give constructive criticism (if you see any mistakes). 4.) Give input (for any ideas for other poses).
You may not:
1.) Use without permission. 2.) Claim as your own. 3.) Recolor. 4.) Post on your profile.
