One thing that struck me straight away was Holly's hair. It looks like a smudge tool (or something to that effect, I don't speak photoshop) was used to an excellent effect as I can't help but look at Holly.
Angel looks as glam as ever, and strangely enough, the mix of her colour scheme with the green works really well.
I can't help thinking that this is subtext, indicating that while Holly might be brash, somewhat stubborn and certainly stands out, Angel fits into any environment and is easily adaptable.
Despite what the artist thinks, I actually prefer the background to this page to the background to his previous page. You know that the characters are in the jungle and most importantly, the focus is on the characters.
One suggestion I'd like to make is that, since this is a jungle, maybe a few little effects might add to the unusual environment. Maybe a little hazy blur to indicate that this environment is hotter than what the characters are used to, or maybe some tropical birds flying in the blue sky in the background. Or even if a character wafts their hands at a large group of flies.
Or maybe a random parrot? Too much? Maybe. But the little details of the undergrowth in panel 4 is very effective, so maybe just a few little details will just add to the sense of being somewhere that's more of a jungle and less like Centre Parks. Not that I'm saying this looks anything like Centre Parks mind! This is definitely a jungle!
