Welcome to DPC. I see this is your second Challenge, and I hope you are having fun.
You have a good range of tones in your image and it is quite well composed. Unfortunately, it is a little 'soft focus' and that made it difficult for viewers to see the beauty of this pretty azalea. And, yes, the voters told you the image is a little small.
I assume you use Photoshop to process your images. It would be worth checking your instruction book to see how to resize your pictures for competition. We are allowed 640 pixels on the longest side and that would have made your image easy to see and appreciate.
If you continue to have problems resizing your images, please PM me and I'll try to help you through it.
Meanwhile, you have a good camera and a good eye. As soon as you get the basic learning stuff out of the way, I think you are going to score well at DPC. Good luck!
This photograph has so much potential but it is just to small for dpc'ers to appreciate. If your software includes resizing, set the longest dimension to 640 pixels. this will help a lot.
A really, really small photo and you've put a border on it. The large the photo the more the impact, especially at DPC. Looks like it could be a nice photo the tone appears to be really good and the leaves look like they are framing the flower nicely. Although it is really hard to make much out.
