It might be your first manipulation, but there's a haunting quality about the whole thing which tells a story for me. Yes, there's a bit of finesse needed in some areas, but the individual elements are all necessary in my view, including both the crow and
I've done a mod for you. It's probably a complete polar opposite to what the others have done, but this is the kind of image that I love. For me, it speaks of love lost, a feeling that the world has lost its colour because of that, of life slipping by in the other direction while the heart grieves ... so my mod has tried to capitalise on that a bit.
I've first of all removed that black bit on the large tree branch, as I spent a while thinking it was another bird before realising that it was a twig of some sort. It distracted my eye, so I got rid of it by cloning it out (a little clumsily, perhaps, but hey
Then I added a graduated colour filter, going from left to right, and using an orangey to darker violet/brown range. This was set to Soft Light blend mode.
On top of that, I added a black and white adjustment layer, played with the sliders a little (I can't remember exact values, unfortunately) and added a layer mask which then had a black to white gradient put across it, going again from left to right until the 'split' between colour and mono ended roughly where her face started. This had the effect of making the whole thing part coloured/part mono.
Then I added a Levels adjustment layer, darkened it down quite a bit and used a layer mask and a large black brush to bring back detail and emphasis where I wanted it (mostly around the facial area).
I then created a stamped copy of the layers (hold down Ctrl+Alt+Shift+E) which gave me a 'virtual' copy of all the layers, as though they'd been flattened.
A brightness/contrast adjustment layer on top of that, with a layer mask and a soft black brush, enabled me to lighten the facial features even more, while keeping the rest of the area behind her head darker.
Oh, and I very slightly blurred the outline of the crow, just to help it blend into the sky more.
I know that sounds like a lot, and you'll probably hate the mod, but I was kind of feeling my way through this process. I sort of knew what I wanted to achieve, but I'll admit it was a bit experimental! The key thing to do with this kind of composite image is to play ... until you get what you want, the feeling that you want and so on. And don't be afraid to experiement ... a mistake isn't a mistake if you like the way it turns out ...
So anyway, enough of my waffle. Have a look and see what you think. It's fine if it's not your cup of tea ... that's what the mods are for, in a way - another possible way of seeing an image through someone else's eyes.
