Love everything about your piece here, with one minor caveat. That of the lighting of the celestial body.
And it is not the lighting, per se. Directional lighting and proportion of.. are good good.
To my eyes, and given the diffuse look and feel overall ... it is perhaps too delineated?
Not sure where it is in the order of layers for your composite, maybe trying moving it 'behind'? If you understand me here.
Composition is strong.
And in looking at the largest resolution sizes, render and post processing performed.. very clean. Great image quality on these notes and overall (i.e. gradation of colours is exquisite ... no clipping).
Very good... the softness and colours of the sky are lovely. It's probably less clear than it would be in a larger copy, but the mesh of the domes needs a slightly more 3D or metallic appearance. Nevertheless, I like the way the domes almost melt into their surroundings. Beautiful scene!
A dock with no boats attached. Solitude knows no more intensity than what this man endores. Even the birds veer away from this location.
