Wow, you did really well with the grass. The water is really nice too but I wish it was just a bit more transparent/transmissive. Nice mood with the lighting. And the model itself is of course impressive.
What happens tho, is that the model doesn’t quite fit the scene in terms of materials/shape+design/scale. The model has more of a fantasy element and realistic but not photorealistic. The wheel could be up to 2 times as big around. The building could be bigger in the scene ( I think the size of the grass is giving the scale). Is there a light in the upper turret or is the sky just that bright? And some of the sharp angles on the turret tops and the wheel might need to be smoothed out to get it more realistic.
Edit: Is that a burnt out stump or a rock? I didn’t see it at first.
