I *love* stories that are written in tight POV! I find them much more natural to read than stories that are written in a more omniscient-narrator style. Everything just seems to flow better when you're seeing it through a particular character's eyes. And in your writing, I always like the way the important details of the scene are filtered through the POV character's personality, so that it feels like I'm actually experiencing it as that person.

But I think what I do need to do, when writing group scenes, is pull back a little bit. I can still be in the POV character's head, but sort of... hovering over him, like a camera shooting the scene from up above

Yes, I can see that if you can hold a wider authorial POV in your own mind, but still write as though it's all being seen by the character, it could make your writing even stronger. But frankly, I think it's already pretty darn strong.
