Cool. More Lincoln portraits, I see. You should keep up at this, considering how well your first attempt turned out.
There are sooooo many forms of art and creative ingenuity. Your ability just floored me. Saying you're no good at other art implies that painters should be talented at sculpture or landscaping or stained glass or origami. Focus on your interests and make your creations your own signature. I'm duly impressed with your first attempt. Keep up the good work and please continue to share your creations with us.
