I think the checkmark is a bit too small compared to the items on the right.
Landscape cards
Here it’s mainly about the placement of the checkmark and the star. Visually already, they look to me as if they’re placed a bit too high. And I can actually confirm that using a screen ruler. For the checkmark I’ve measured 12 pixels to the top and 17 to the bottom. For the star, 8 to the top, 14 to the bottom.
I realize that all of these things may sound a bit nit-picky, but why not throw it in here? Even an ever so slight improvement to this would be good and not hurt anyone.
I’m a Web Developer and did a little more research for you. They have certain CSS applied to elements like theses.
For starters, the Star icon has a -2 pixels applied to the top for some reason. If this was removed the Star icon aligns much better with the rest of the icons.
As for the Checkmark icon, the CSS is correct…I believe it’s just the actual size of the icon that makes it look “off”. They are using a mixture of icons, including their own font icons…so maybe they can redo the actual checkmark to look more consistent.
