The first rendering is beautiful and has the perfect composition and belongs in the showcase section for the quality and craft in the image. As for the second image the chairs and pink glow immediately catch the viewers attention.
I would first just change out the texture on the chair legs to something with either smaller grain or a finish/painted look. Then I would add a bit more blue to the image, even though you are trying to capture a beautiful pink sunset it is going almost into an apocalyptic pink where I expect a thick haze to be blocking the sunlight. A glow like this is more accurate https://unsplash.com/photos/_pPHgeHz1uk From here you should have a really nice looking render and the only final touches I would suggest is playing with the aspect ratio or field of view for the image to make it more āphotographicā in nature. As well as, adding a more realistic vegetation in the foreground planter. Another final touch would be a few of your surfaces seem to be over reflective compared to reality. donāt bring them all the way down to nothing but a subtle refraction of light would boost the image quality and make your lighting even more provocative.
I agree that the first render looks very good, although the borders of the table and of the wooden tray look a little bit off. The glass on the right is half in focus, half out of it. Same with the bottle of wine. It would also be a good thing to try out other angles from that scene.
.. But, are you selling the terraza, or the steaks 
I agreeā¦ Sometimes we get carried away while styling. The scene is overpowered by the assets.
For me .. beauty.. Iā a rookie, But still some things I can notice..
First image
most obvious to me is the repetitive texture on the left side edge of the table.. the rest I dream of that level..
Second image
again repetitive texture on the floor, edge of table.. walls look ok to me. Chairs in front of the table all same.. You donāt have to make another but maybe flip the middle left to right and slightly turn the right one 5deg or less.. should give enough different look.. Same with plants in front.. those You can randomly rotate any amount and it should give them already some variety and more realism.. maybe scale bit down or up some.. it is not often that You can see two exactly thee same plants.. even rarer three.
the blacked ribbed walls on the right.. I guess black is on purpose but as well I think it is not the point of making so thick ribs to have it look almost completely flat. maybe some extra fake light lightning it a bit from the side somehow would show more details..
What is this beam of light from the column on the ceiling.? I love the wooden ceiling BTW..
