You're right, the sky is noisy. I still have to find a way around this issue, as many HDR pictures I've seen have noisy zones...

And btw, no offence at all my friend, we're here to learn from each other

I forgot: the sky is not very detailed because of the long exposures used... the clouds moved a little

Beautiful image and very nicely composed

Since you asked for a advanced critique, I will share a couple of observations/opinion.

There are several spots in the sky, which suggest that your senor is dirty. I use the Healing Brush Tool in Photoshop to remove these, IMO it does a better job than the Clone Tool. There are some who believe using any Cloning Tool is a manipulation, but I don't agree when it comes to removing senor spots.

There is fringing along the domes and building where the structures and sky meet. This usually happens from over sharping, to much noise reduction, contrast masks and/or even the HDR process. I would use the Lasso Tool and the Clone Tool to remove it.

Of course none of this is necessary unless you wish to make larger prints

As for the 'noise' in the sky, the long exposure with moving clouds and then combined with the HDR process brought out some unwanted details, then maybe to much sharping, and you have an unusual or noisy looking sky

It still a beautiful image, but you did ask

I can’t provide an advanced critique but I will say that I like it! I did enjoy reading ernieleo's critique though.

Thankyou!

same as ernieelio so won't repeat.
I like the glassy feel and beautiful strong colors. Also the clearness.
Looks neat and the framing please me. Overall, great shot
