this is a good photo but I wish it was bigger, both in terms of the image size but also in file size. The max limit for file size is 150 kb and your file size is 79 kb, this means that you could have had a much larger file size which would bring out more details int the photo. Here is a link to the tutorial on submitting photos for challenges. This is based on using photoshop if you have it. I see lots of photos marked low because they are small photos and file size rather than judged on the merits of the photo itself. Hope this helps
great idea, title, however there is something a bit off that leads me to wonder what you used to shoot this, i'll know tomorrow, but until then, good job
