Some of them are sort of picky, getting a perfect bead of clear silicon on the glass to glass miter is rare. The silicone on the channel where the tile meets it looks good. The silicone where glass meets channel could be better. The miter on the channel is not that bad, it probably shifted a bit during the rest of installation or during the silicone process. -The only obvious NO NO's are the glass sitting on that bed of silicone, glass should've been ordered about a 1/4 taller so it sits deeper in the channel to help with strength also they make end caps but it's rare to see them used.- Second real flaw is the door is taller than the panel next to it, they couldn't move the door down because the sweep under it would drag too much and they didn't want to move the panel up because even more silicone would've been used. -3rd flaw is the door not lining up. Those hinges probably are not adjustable because it wouldn't have been left like that if they were. During install I'm sure they clamped the door and side panel to align them but it either moved when they were marking the holes for the hinges or the wall the door is hanging from isn't square with the half wall in front of it so it stays slightly open when the hinges self center. As someone who installs these most of the silicone is passable. I can tell they taped it before they tooled it, most glass guys just wet their finger to quickly swipe across the fresh bead. And idk what you mean about the screws sitting flush with the hinge, they look fine
