I have to say I find some of these station designs to be fairly uninspiring. They work, sure, but it seems a shame for all of them to be glass boxes surrounded by a concrete plaza. I'm most familiar with the areas around Great Northern Way and Mt Pleasant/Main Street, so I find those stations particularly at odds with the surrounding character.
With Great Northern Way, it's an area that historically was on the banks of False Creek, and then an industrial area. Lots of the redevelopments there have made nods to the style of those industrial buildings, and I think the station could do similarly without compromising elements like visibility and CPTED.
They could use painted brick or corrugated sheet metal around solid parts of the exterior of the station house, like the Canvas building across the street did:

Rather than walls of plain glass, they could take inspiration from the garage-style doors of the (to be demolished) Equinox Gallery building:

Public art in and around the station could make reference to the St George rainway, Brewery Creek, and the filling of False Creek for rail yards.
I realize they're leaving space for a future development there too, but I find it somewhat ridiculous that the entrances to the station lead out south and west to Great Northern Way and Thornton Street, when most people exiting the station will be wanting to head north or east towards Emily Carr university.
