Lovely! I really love cat3 too, so simple yet interesting with a lovely subtle coloring and contrast.

My other favorites are Hands, Pale Background (great coloring), Nostalgia (lovely coloriong here too, and the image is nicely clear and crisp!), Pride, Cat2, Cat3, AC1 (love the levels look and the font), AC3 (love the crop and the bright blue coloring), ac5 (great image quality). All the alts are great too. ^^
