Wow! Bong Bong!

Without context, the pose is a little odd, but the basic proportions and placements are close to where they need to be, but the proportions aren’t quite on model. This could work with some adjustments on a redraw, but the main issues are the facial proportions/placement and her left front hoof not being attached to her shoulder.
 
Did you do any construction sketching on this? It helps a great deal to avoid skeletal errors.
 
Think you’d be up to doing a page of five construction sketches without doing full detail (hair, mostly)? It’s a great way to practice proportions and body language for a character without getting distracted by the final details unless you want to finish some of them. Either way, seeing how you sketch would be helpful on critique.
