Too many rules in this thread.
Obey rules, and your images just look like everyone else's that obey the same rules.
Feel the force Dude....
Personally I like the first one, without any cropping. What makes you think you needed to crop at all? It's a shot of a horse, so you need to make the horse bigger? That it? Sorry, but the horse alone is boring.... it's a horse.... seen a million of them. The first one is the horse & environment, and the framing of the trees is quite pleasant.
All you're doing by cropping it, is ruining it IMO.
