I'd like to see this one again, with a viewpoint closer to the rack and with the black lines diagonally composed - I think that would make quite a dramatic, dynamic shot.
Impact-wise, it would have been more dramatic to shoot the rows of glasses head-on to make straight horizontal lines. Nonetheless, I find this display quite appealing.
Image is quite heavily compressed (pixellated). Apart from that I would prefer either a more acute angle (so that you were closer to some of the products) - or a very square face-on view which may present the shades in a more striking way with horizontal lines offerig the feeling of 'infinite' lines to right and left.

This is a nice shot - I like all the colors and the pattern. I think I'd prefer it without the brands at the top as they add little to the photograph. It depicts stylish sunglasses and to me, that's enough. Also, I see a lot of jpeg compression. Try to save at a file size closer to 150k.
