I finished the LMNOP crew!

Explanation (FYI, see the pony types):
P - Speedy, skinny, and hyper pegasus mare. Ponified P fits to be curly, just like Pinkie Pie. Cotton candy 😋. Based from this pony's body (Loosey-Goosey). Her cutie mark is a cherry pie.
Q - On the other hand, Q is slow, short, and intelligent abada stallion. Sadly, there are no "slug ponies" or "snail ponies" in MLP universe, so I choose Abada, a Central African mythological creature instead for ponified Q. Abadas are very tall and fast, but Q is the opposite parts. Due to his short legs, he use a wheelchair. His cutie mark is a slug, definitely. Note that I drew his body/base by hand drawing.
R - Arrrr! Remember that I did the pirate R? One of his eye is blind. He has weird cow prints in his body. His cutie mark is raindrops. R is not short in the image, he opens his legs btw.

I traced them in screencaps, can't credit bases because it's very negligible.
