Sweetie belle doodle from a couple of days ago.  Also a critique are would be appreciated. \0/
Now this is what I love to see! I can see the under sketch, and the finalized lines you've made, so I can see the improvisations you've chosen to make, as well as liberties you've taken with your style!
I would love to offer you a critique!~
Your pose is fantastic, it's original and unconventional. Two big things people strive for. You anatomy looks on point, as well as size of most things.
Now before I start with things I feel could be improved I'd like to simply point out things I notice with your doodle. First big thing is I can tell the way you do your nose is a style choice, and it's very nostrily, which is cute. Your ear is also done in a unique way, different from show style. Then the last bit is the mouth and eyebrows are very animated and cartoony. Where the eye brows are leaving the face and the mouth is pushed so far up it's right below the nose. Both those things are a very cute touch and play really nicely with your style choice. I love the eyelashes, it's again not show style, it's unique/different, which I dig, it's very cute. And I love the hair, super cute.
Also I like how the nostrils are raised like the eyebrows, they are mirroring them, it's almost like shes flaring them and they match her expression. Hehe. And On that thought, I could totally see her sniffing something like a delicious pie with this pose and expression. And now I can't un-see it. That's what it is isn't it! ADMIT IT!
Now things I feel you could improvise:
SB's front leg that is down joins to her body at a very high point, I like that her shoulder is raised it really adds to her smug expression and posture. Very prissy and adorable. Very contrapposto if you know that word from your art school. However it also makes her front leg look extremely long.
Then I can't tell if you were giving her hooves or making her raised legs longer, if you were just lengthening them, just remember to erase those lines and ignore this comment lol. If you were giving her hooves, give it to all her limbs.
Now show accurate fillies (For your more original style you can ignore this, I'm just mentioning a point) their legs are very short and their heads are huge. So for this style you have here with the long legs and neck it makes her look a bit older, almost grown up / teen. So that's just something to be aware of, where if you want to make something look younger, you give it smaller legs, body, and a big ol' head and eyes. Bam, filly.
So the big thing is just be careful with legs and you're golden.
THANK YOU SO MUCH BRO for the submission. And Ty for doing that interview with us. I'm still trying to get that up. My computer has taken a crap on me and wont let me render things recently and I've been working on it.  My apologies. It's coming.
