The choice of subject is interesting. Keys can provide for some nice textures and patters.
Using flash and the only source of light can produce some very harsh shadows as can be seen on all sets of keys here. The most distracting shadows appear on the left most ring. Softer lighting I think would improve the overal feel of the image as well as help bring out some of the textures in the front most keys.
The placement of the key rings works quite well but the composition could possibly be improved by raising the right most ring slightly and lowering the other two slightly in the frame.
A fairly pleasing image.With so many keys I'm sure there's several arrangements that could produce pleasing images.
