How many comic panels are too many...

I've been playing with this on and off, how many panels can you do before something gets too crowded or becomes so abstract it is no longer stylized the same way as the rest of the book? In the comic I write, the most I was able to pull off was 8 panels. (examples below)





These two were pretty successful, I like the first more than the second. I've seen books with 9 panel grids and even more... I'd love to hear some opinions on this sort of thing. Can I do more than 8 panels without things falling apart or becomming a puzzle? If 9, 10 ,12 , 15 panels are doable what would be the sort of scene, scenes for this? (I'm not going to do it just to do it, there has to be a reason behind it of course) Can a page say, with all sillouettes work ok in this comic? Will very small drawings work ok? (especially since a majority of the pages in this story have larger images. I'd love to hear some opinions
