Dragon Drawing Advice

[Remmie Moore 9]

Hiya,
 
I decided that a dragon OC would be kinda cool, but the only dragons to reference are babies, teenagers and GIANT DRAGONS, none that are adults but vaguely sized to deal with ponies. I don't know why, but the shape I went with just seems off. I'd appreciate any critique or advice in drawing a dragon like this (and I know, I'm not doing the typical colour palette of MLP because doing each section with a different colour takes a lot longer for me and I prefer this style for drafts).
 
Thanks in advance!
