So yeah, might be better that I just put up a thread and then just hope someone will pick it up. Fortunately, this isn't a very demanding request.
 
Note: Because I'm not 100% on her design just jet, feel free to tweak some minor details if you so please. Alright, now to get specific.
 
---------

Image type: Sketch (you choose if colored or grayscale)
No background necessary.
 
Species: donkey
Gender: female
You may use Matilda as a reference for the overall body shape (1) (2)
Just one caveat about body shape, however. Try to make her appear physically fit. Do whatever you want to make it work.
Mane style: Apart from being longer and messier/scruffier, not too different from her twin brother's
Tail: also messy. Tip of the tail looks like a small flame.
 
Eye type: normal. Color of eye lids blend with her coat.
 
For a black and white sketch:
Coat color: pale.
Mane color: slightly darker than coat
Eye color: Dark.
 
Her actual colors (just for clarification or just on case you do choose to make it a colored sketch)
Coat color: Copper
Mane color: Light brown.
Eye color: Deep brown.
 
Facial expression: Stern.
Posture: Whatever goes well with her facial expression.
Accessories: None.
 
Hope you'll enjoy the ride. Take as much time as you need. Better late than never, especially considering it's your choice if you're going to do it or not and considering that you're putting in the actual work.
