Why don't you have a reflection for the doors, why are there windows reflected where blue wall would be? Why are there 14 rows of reflected windows, but only 13 rows of windows on the building itself? Why aren't the railings for the parkade/dock reflected on the ground as well?
How many people can fit in the building, and how many people can actually get there?
- It looks like there's docking space for 2 to 8 boats, depending on size, but there are hundreds of windows and presumably hundreds of rooms.
Where are the exterior lights?
- If it's evening, it would be good to have some lights around, so the boats can see the hotel and dock, and the people at the hotel can wander around in some light.
I think you'd benefit from thinking logically about your hotel, as if you were actually going to build it! Right now, the concept is very cool, but it looks like an office building on a lake with only one door and no roads going to it. I imagine you mean for it to be a resort/luxury hotel, so I'd do a bit more to show that, such as showing what people could DO at this hotel (There could be a very nice restaurant on the dock, a few trails going through the forests behind the hotels, and a beach somewhere for the clients to stay at).
Also think about how people can get places. What would happen, for example, if a boat was too short for the people on that boat to actually reach the dock? They wouldn't be able to get onto it, so I'd suggest a ladder or eighteen to help people actually board the dock. Also, the roof of the building looks like it'd have a spectacular view. Wouldn't it be good if people could get up there to take a look around and relax? If they can get up there, you should also think about their safety, so railings would be a necessity, at the very least. There could even be a pool up there, though that's a bit clichee.
In short, there's plenty of places you could go with this. I suggest building on to the concept itself before you worry too much about how the water will look and whether or not it appears to be evening or daytime
