Study of a foal – acrylic paint

Today I wanted to make a painting out of yesterday’s study of a foal. At first I thought of watercolour, but as I tidied up my pencils, pens, paints and paper in the past few days, I thought I could give acrylic paint a go. I have little idea of the proper techniques so I just tried painting with blue. Here is the result:

I especially like the neck, with its soft shadows. I painted several layers over the legs, but I’m not as happy with them as with the neck and head. Any tips from more experienced artists? Just type a comment below! I’d be very grateful for your feedback.
