Carthago

Hi!
Good start as always, but much to comment !
-the road will need to look texturize, be it sand, gravel or pavement. It's too clean like that.
-I think the sea horizon needs to appear a bit more. Just contrasting sky and sea a little bit more between each other.
-the city looks pretty good. Maybe some ornamental painting would characterize the wall. And if you want to have the gates opened, having one of the timber gate panel visible (the left one), with a guard and some horseriders or people arriving or leaving the town.
-The big sail is too dark/dirty for a war boat and for that lighting, I think.
-The sky feels a bit too complicated, and at least unrealistic, to me. The rays from the sky are looking good. I would just simplify the rest of the sky with a single blue fading to orange. I know it's not simple, and if you don't feel inspired by this remark, well, keep the sky like that.

To inspire you for realistic sunset lightning, here is a photo I took in Greece last summer : [link]
and here is another one from my french countryside : [link]
Oh, and here is a very nice internet photo of a typical "palm + beach + sunset", helpful too : [link]
