varied angles to provide emphasis, so long as they're executed well, can actually do a lot of good when added to a comic
it's not a piece of advice i think is shared often enough but using things like film or tv as inspiration or reference when framing comic panels can be very useful. not to mention the fact that having varied panels helps to keep a reader interested in what they're looking at
if you're looking at a conversation with nothing but shoulder or wait up shots flipping back and forth between the two characters talking you're going to get bored but if the focus switches to elements within the room/space that they're in, portions of their face or their facial expression (furrowed brows or a crooked smile) it adds intrigue
The same can be applied to action scenes where scale or impact can be shown by how far the "camera" zooms in or out, showing intensity by focusing on the characters or their weapons.
Looking at other comics for reference to see how to apply it can help but i'm a firm believer in mixing up panels and angles otherwise you risk having a very dull looking comic (unless that's the intent)
