To many details in the same image. If you use so many details in the close up don't use also cumulus clouds in the back . They for form outside of main land. In this case on the seaside .
Sometime : Less is more.
The images could be great if had different clouds in back .
I completely disagree with you here.
It is clear that the artist didn't go for a traditional 3 plane composition here with blurred foreground and background, but instead chose to portray the architecture and the landscape in all of it's glory. With that in mind, I believe that having a dramatic sky and lots of details in both textures, entourage and key objects of the image makes it visually and conceptually interesting and contributes to the overall story. While quite often having this many dominant colors and/or textures in an image can result in imbalance, I would say that this time they do play together really well.
Great job on matte painting the image! I always love a little bit of a side-story in architectural visualizations :)
