Welcome to Gaia! ::

I think you're a good artist but... I'm not sure how that even relates to dressage? The horse is behind the vertical and wearing illegal tack...

lol, no problem! Sorry, I just get kind of touchy when people present horses as doing "dressage" just because their necks are rounded. A horse correctly on the bit should be reaching into the bridle with their nose on or slightly in front of the vertical. The mouth should be softly closed and the horse should work the bit softly while working. Lower level horses should have a single rein attached to a smooth snaffle, and FEI horses ride in a double bridle, with one rein attached to the bridoon (snaffle), which is kept in contact, and a second rein on the weymouth (curb) which is kept somewhat slack and used for further refinement of an already finished horse. Martingales are not allowed in any level of competitive dressage. Running martingales are acceptable in the warm-up ring, but highly frowned upon. No other artificial aids may be used while on the show grounds.

...and I'll stop now. xd I'm mildly compulsive. It is a very nice drawing though!
