I think they look good, although I think I see a spandrel grid at the penthouse levels.
I think the east tower should be flipped to face east and the south tower should be rotated to face south.
There's a bit too much repetition with than all facing west.
If the vertical cladding on the towers demarcate the office floors (west tower) and hotel floors (east tower) - those spaces are not huge.
The Daily Hive story calls it an "early design" - so hopefully it has improved since.

There's a faint resemblance to this Toronto project:
