Very large scale view on this photo. I like it a lot. Very watercolor like. Great job.
What a great range of colors captured. I like the tree on the right side of the image. It almost looks fake, its so vibrant.
Nice sunset and undulatus clouds. I like the 1/3 placement of the sun and the amount of land included in the frame. I do feel like the editing was too heavy handed and seeing how pretty the original photo was don’t feel like it was necessary to stray so far from what was originally captured.
I love this image! I really like all of the colors in the sky, from the yellows and oranges in the distance to the darker purples, blues, and even a little green in the clouds that the sun has yet to contact fully. It creates a vibrant range of contrast in colors. Looks like a fantastic morning in Boulder!
1. The image is artistically vibrant and well done.
2. The physics are well shown.
3. The photographic post-processing is really nice.
Incredibly stunning color. And the direction towards which the camera was facing is also perfect.
What a beautiful sunrise! I really love the rippling effect of the clouds in the upper right portion of the photo. It looks like a sunrise straight out of the Lion King movie looking over the African plains.
The clouds are gorgeous and the colors are stunning but I think you lost a little detail in editing.
Colors are gorgeous but a little blown up in my opinion. The yellow especially looks a bit unnatural. Love how reds came out but a little too much in my opinion still. The black tree on the right is a nice foreground element. Great focus!
Amazing image! The sunset take the white cloud into red and yellow color.
Reminds me of the lion king sun rise. I like the tree on the far right, it adds a great touch. The reflection off the lakes is well done too.
Really dramatic colour! The variety of clouds and colours make the image interesting to the viewer for a long time. I like the shadowed tree on the right, but did you consider removing the lower branches to have a cleaner horizon?
Great shot! I like the way the cloud guides your eyes to move across the picture left to right. Good framing but i think the contrast is a little high on the edited shot.
Wow!! This is a fantastic image, because of how full the sky is with the clouds it really lights up the sky with a nice bright color. I like the tree addition on the right side, and the reflections on the sporadic lakes.
Art: I really like the color contrast of the clouds in this picture, the colors and the cloud forms are really interesting and pleasing to look at.
Flow: The flow is quickly understandable and easily recognized.
Photographic technique: The focus of the clouds is great as well as the colors captured is perfect.
The colors in the image are amazing, based on looking at your original image, I can see you did some creative post processing additions, so good work bringing out the colors and textures in the final image. I also enjoy the contrast between the smooth, cumulus formations and the sharp focus in the pine needles on the right side of the image.
Great colors shown here. Almost too much photoshop was done I think. Some of the depth was taken away to bring out the orange. But the lakes and tree gives a nice feeling.
Colors are incredible. I think you need to tone down the curves. Slightly to much editing
I really like the deep sunset colors that contrast well with the foreground. Very beautiful and aesthetically pleasing.
Beautiful bright colors. I like the amount of detail you were able to capture. Awesome sunrise.
Ripples in the center of the image make me think of patterns waves make in the sand, really stands out to me as the highlight of your image. Great job capturing the whole range of color and brightness here without blowing out the sun, that’s no easy feat.
Awesome colors in this image! Cloud structure is captured nicely and the timing for this photo is excellent.
Really great color in this photo. You can really see the texture in the clouds. The ripples on the near cloud remind me of sand on the ocean floor. I also really like how the tree adds to the photo.
This looks like it was taken out on the edges of a desert, beautiful image. The sparse trees add a really nice effect. Ripples in the clouds are nice, and the vibrancy of colors is excellent.
