Here's Tim the kangaroo as sketched by  ahro, with ink and colouring added by me.

The basic sketches are available each month from her patreon in the $15 tier and above. Supposedly every three months you get one that she's coloured herself, but since her patreon has only been running for two months this hasn't happened yet.

In the original sketch the neck kind of tapered off, but his ponytail was still visible behind the neck as though he'd been beheaded or was a fursuit head instead of a real person. This disturbed me so I improvised the shoulders which don't look quite right but stops him from looking like a decapitated android.
My colouring technique is flood-fill based, so I need bounded objects to work on, so this has been a bit of a learning experience. Next time I might try fading it out instead.

The carnivorous teeth are a little unusual for a kangaroo, but on the other hand Beings are omnivorous so that works for me.

In any case, I love her art-style.
