This part almost never came to be, because the Photoshop file corrupted itself and wouldn't open. Fortunately, a freeware Photoshop Recovery download managed to pull out all the artwork and merge into one layer, so I still had something to work with after 12 hours worth of colouring. What a relief.
The as-of-yet unnamed female newcomer was the most difficult part to pull off, since she's the first female ungulate (hoofed mammal) I've done in a long time. She's supposed to be an oryx but I tinged with brown so she didn't look, well, dead. I don't endorse smoking either but it'll make sense later on as to why she does that.
With thanks to
who actually did most of the donkey work with the base colours, which I later built up upon.
