There!
Sheesh, Celestia is quite the hassle to vector. To anyone else who has done so, I feel for ya.
Anyway, according to my rough estimate based on the same screenshot of Trouble Shoes and Applejack as last time, and this screenshot of Celestia and Twilight, it seems to me that Trouble Shoes is… well, still a giant. If you include her horn, then she might be a little taller, but as far as I can see he is larger in every way. Maybe if you include her mane and tail to her total mass, she would outweigh him. XD
Celestia was traced from this screenshot.
Trouble Shoes from this one.
