Arabian Horse - Acrylic Painting in Progress

I wanted to go back to an acrylic medium for this large painting of a running Arabian horse. Actually, this is just a portion of the painting, which is a 40" x 60" stretched canvas. Obviously, this is still a work in progress, as I have not added facial details, flowing mane, etc., but I wanted to show you what I had been working on for a couple of days.

I'm trying to break out a little, in terms of use of color and fine blending...you know what I mean...I really want this to be more impressionistic, energetic and modern, rather than traditional and tightly rendered. So far so good. Just need to stop myself from overworking it!

Thanks again for looking.
