Doodle Dump 9/7! Moar ponies!

Would you guys be interested in me doing doodle dumps every day/other day? And would anyone commission me if I opened them?
Commence self-critique!

1. Ribbon Rhythm, my oc! You know you're a terrible artist when you can't even draw your own oc... orz She's missing wings yay
- body too short
- hooves are weird shaped
- tail is weird (derp)

2. Fluttershy~ Tried following a tutorial with her. No wings.
- body's too fat & short like a stallion
- mane is too thin
- tail is weird
- legs are kinda fat

3. Another Fluttershy. Missing wings again.
- mane too thin
- tail's weird
- raised hoof is awkward (still working on that)
- snout too long
- ear is off
- hooves are fat

4. Twilight missing her horn! At least the wind's going in the right direction this time!
- mane is too mushroomy
- bottom of back hooves should be more rounded
- back of knee cut is too deep
( i really like this one though)

5. Yay Pinkie Pie!
- mane and tail don't seem right
- leaning forward (thought I didn't mean for that to happen...

6. Princess Cadanceeeeee yayyyy~ she was rushed in like 1 minute LOL cus I drew her on my test
- Mane needs more swirls, needs to be wider
- tail is completely off
- hooves are wrong shapes, different length

DID I MISS ANYTHING? TELL ME! Trample on it, kill it with fire, etc. I wanna hear what you have to say!
