Seen a lot of people draw their own interpretations of what the mane six would look like if they had more unique traits. Decided to try that myself.
Here’s my take on AJ.
Her body type and coat colorings are inspired by a mix of the palamino, pinto, and belgian draft horse. Out of the mane six, she would be the tallest, even when Twilight reaches full alicorn power and status. AJ never quite gets to the height her brother stands at, but she would tower over her mother if she were alive. She may be great at bucking apple trees, but she is also strong enough to plow fields on her own. She is married to Rainbow Dash and they live together on Sweet Apple Acres.
