Pony WIPs

I'm really torn up because I'm going to BroNYCon in what two weeks? and I reserved a table for Artist Alley but I completely hate how I draw ponies. ;.; These were some things I started drawing up to use for stickers, bookmarks, dunno-what, so I was hoping to get some kind of feedback before I go forward. (I mean I've done SIX PAGES worth of drawing ponies in this style so it would be nice to get some feedback before I ink those, I guess XD)

I know they don't look like they do in the show, I just don't want them to look completely weird or not like ponies at all..? I don't know. I just don't like how I do them but so far I've liked this look best. Please let me know what you think.

(Also I do have to clean up the lines, they're horrible but I scanned these and posted them right from the sketchbook.)
