That's a very good design! I especially like the wings: their facades and the bit irregular roof. The circular part looks more like a sports arena to me than a transportation terminal. That doesn't I don't like it. I'm wondering if it would need more support, though.
Transportation terminal interior looks great! I especially like the roof and the back wall. Do the curved pillars have any structural function or are they just decorations?
The last one is quite an interesting setup and good job also on the WTC facades.
The Alora Tower is just the kind of 21st century architecture I like: pretty simple basic form but very interesting facade. The short sides of the taller building make it very sleek looking even though it's quite wide. I also like how well the base and the top fit together with the shaft.
The shorter building compliments it's taller partner very well.
The shape is very nice and the detail is great! It also seems to fit its location very well, although it's difficult to tell exactly, as the surrounding buildings are not textured.
You're renders look very good. May I ask what software you use for modeling and rendering?
Alora tower is greta reminds me of 'Tokyo' style, with simple geometric form and attention to detail on the facade, good job.
Atria looks very good already even in its unfinished state. The subtle curve in shape and the way you are detailing the exterior give this a realistic and very well considered appearance. I look forward to seeing finished renders. If you can add more details to the context/surrounding buildings that would help the Atria 'settle' into its background more, but again good job.
