Hi Yasha, you are a very talented artist just waiting to emerge. You can draw beautifully and your eye for color is revealing itself as evidenced by these last paintings. No matter that they are copies. Keep at it, the more you practice the more you grow. Challenge blogs are a great help in stretching your abilities. Try these other challenge blogs: Rookiepainter; Virtual Paintout: A Day Not Wasted; Studio Atelier; Paint and Draw Together if you haven't already found these great places where artists of all abilities and styles come together to grow and have fun.
