Yes....these are lines....but its so un-interesting! I'm not trying to insult you, but simply give you feedback that many probably are not giving you. This image is a simple pattern and lacks interesting composition, as well as a subject! I have no idea what kind of rating you're getting right now, but I'm sure you would have finished at least 50-100 places higher if you had a subject. Picture a ladybug crawling along one of the lines....even a leaf that had fallen into the grill.....maybe even a curled up burnt hotdog with grill lines on it on the edge of the frame. I've given simliar comments to other people who submitted line patterns with no subject. Just my two cents. Hope this helps.
