The crane looks good! Barrels a nice feature.
I think you need to decide how much detail is going to be visible in your animation.
That is assuming the only purpose of the work is for the animation.
If it is relevant to the detail worth doing. These are my thoughts.
The slopes in the paths I think need to be flattened side to side, across their width. Thinking in front of the second row of houses.
The steeper sections going down the slopes to the wharf-side and on up the hill from the bridge probably should be stepped, they are too steep to be usable slopes.
All your beams are square.
The dock wharf. I have tried looking for images and can find nothing much at all that has the diagonals. If at all they are used inwards. They just look wrong to me. Like the same issue with the crane base. Where if anything there are not enough, bracing would need to be Xs all round? All the wooden wharf images I saw had solid planking, not your huge square beams edge to edge. The crates, I would jiggle about, a bit less perfectly stacked up.
An alternative wharf, brick/stone built.
The houses have no ground floor windows, and the doors have an odd central protruding plank. I would replace the doors with a single flat object and of a different wood effect, making then stand out a little better. Plus the doors are too wide, nearly square. If you narrowed the frame, moved then left or right, there would be space for a (non square) window at the ground floor level. Personally I do not like the lots of the same square ends to main beams showing. The roof ridge could be shaped more like a row of ridge tiles? The beams supporting the middle house upper story overhang could be narrowed vertically, even a couple more added then.
There is grass in the cobbled/stone paths and in from of some hose doors where people would be continually walking. You could weight paint it off such areas.
Just wondering now if there is too big a drop from the wharf to the waterline.
These are my feelings were it my ‘world’, not necessarily right or better. It’s your world and how it is meant to be, not mine.
