How's the lighting on these??

First is best. I dont like the overall angle of the second shot

The lighting is flawless, exactly what you need for art pieces. Unfortunately, that kind of lighting also flattens and dulls the colors and contrast of the piece. To really catch the judges eye it needs more "pop" to it. Try upping the contrast and colors (while still maintaining the art piece's integrity) to get the piece to stand out more.
Great shot though, magazine quality!
