Love it love it love it Liz!!! Well done I'm very impressed
Only other main thing you need to learn with pastels now, is just how to get the detail of the outline of the drawing, it's a little fuzzy on the edges so to speak around near the forelock, but that will come as you use pastel more, it's hard to get fine details ;)
Absolutely beautifull though, the owner will be very proud to have had you draw her foal, it's just lovely!!
