Simple Horse Sketch

This is a simple rough sketch of a drawling that I am working on, and when it is finished it will have a back ground as well as quite a few details added, I have a decent idea of what I want to do for the back ground and I do plan on adding more details to the horse so that it seems more life like. This is a simple pencil drawling, simply because I love using lead pencils. Please do let me know what you think, as well as what I could possibly change or tweek just a bit. Thank you.
