You've got an unbelievable amount of JPEG compression showing here. Fortunately, due to the nature of your scene, it comes off looking more like an artistic treatment than the compression artifacts that this really is showing. At 28k file size, you had a ton of overhead you could have used. I'd love to see a version of this with less compression. It looks like it could be a wonderful scene. Always use the least compression you can get away with and still come in under challenge limits.
Cool photo with appealing textures, abstracted nicely. This suffers, however, from a lack of sharp focus anywhere and a lot of JPEG compression artifacts. Makes me wonder if it was taken with a cellphone.
while you have all the ingredient to make a lovely photo it just does not work here due to the poor image quality. Particularly where it is a little bit blockish, it is obvious you have a good eye but maybe some slightly better gear would help.
