I omitted a few things [martingale] and some things I edited to look more like the "real" Summer...but basically...whaddya think?
I'm not happy with the mane at all...UGH it is totally my Achilles Heel - I feel like my drawings would look better if I could get the mane/tail/forelock to look more lifelike. -_- The owner asked me to "draw it straighter."

The bottom of the neck also got messed up...not quite sure what exactly happened.

Have at it, guys! I love hearing critiques, it's how I get better.
