Second painting ever in acrylic

Thank you for your comments, and in response, you are correct in the presumption that I have sketched before and that this is my first venture with color. I agree with your assessment of the hair, but all the attempts that I made to highlight it or give it some sort of texture seemed quite contrived, so I ended up covering them up. I see all these wonderful examples on this Forum and am quite intimidated by them. But I hope that putting myself out here will enable me to learn more about proper technique. I plan to experiment with oils but find them to be rather pricey for me to use regularly; perhaps they will improve my work enough that I could afford myself the luxury.

Thanks again,
Elijah
