These are altucumulus clouds near the CU Boulder campus. Taken by my iPhone X at 5:14 pm, August 29. Meta data: Focal length: 4 mm. F number: f/1.8. Exposure time: 1/12,048. Below is the corresponding Skew-T diagram. The CAPE values in the diagram suggests that the atmosphere was not stable at the time.

Could use a bit more contrast, but looks good!
Love the focus, great image!
Great picture! I think you could increase the contrast to make the clouds stand out a little more from the sky.
It looks very celestial! Loving the rays of light.
I like the focus of the image.
I like the sun rays you were able to capture
I enjoy the viewing angle of the lighting. It gives the clouds a good contrast!
I like that you can see the layers of the clouds with the darker section on the right and the lighter section on the left.
The crepuscular rays that you captured in this image gives it some great depth.
I like how you left the thickest cloud on one side giving the photo a good flow
I appreciate less post-processing in this photo. It looks very natural, and the natural shading and dispersion of the light against the clouds is beautiful.
I’m impressed at the shutter speed used. I like how you were able to capture clouds at different altitudes. I like how this image was not edited, as it shows the natural beauty of the sky and the clouds.
I really like the effect the sun has behind the clouds, it gives the image good depth and variety.
The focus is quite crisp, and I like that these clouds are not as common around here.
I like the lower sunrays in the images. I enjoyed how the clouds interracted with the backlit sunlight..
Did you do any editing or post-processing with this image? Looks great!
The gradients of blue and the sun rays are really nice to look at! Also it seems like your reading of the skewT diagram accurately reflects what we are seeing in the photo.
lovely clouds. Great photo without any distractions.
Nice photo – very natural photo of clouds
I like how you can see the difference in water vapor between each cloud!
Great knowledge! I am impressed with how much you know about your cloud.
I really enjoy the depth that is depicted here. Very well done
What direction where you facing when taking the photo?
This reminds me of a very calm summer day! I think you did a great job capturing the rays of the sun through the clouds.
I like the range of light and dark sections as well as the visible sun rays.
I love how light the cloud looks! Gives a very cheery feel.
Very nice spotting the darker spots in the clouds and interpretation what that means for the atmospheric conditions during the time you took the picture.
Very cool image. I like how you can see several different types of clouds in the image, which is reflected in the Skew-T diagram
I agree with your prediction that these might be alto cumulus clouds. I like the way the sun rays shine around the clouds
I really like the depth you were able to capture with the sun and shadows on the clouds
