Thank you for that wonderful substantive edit Cyangmou! Super psyched looking at your changes, you really honed in on the elements I forgot about or got lazy with.
I'm not quite done with the edit yet but I wanted to get something down before my week of study started.

One issue I have in general is creating heavily hue shifted ramps with very little tonal contrast out of habit (and perhaps colour blindness). However I over compensated with this picture and made everything a way too bland, your edit really pushed the colours in a nicer direction. I didn't push it quite to the same extreme but even still, the picture is really popping now.
I love love love what you did with the clouds. My new ones are still a touch rough but I feel lousy about not giving them any attention before what so ever. I tend to treat backgrounds as an afterthought, a habit I badly need to break. I think i'll likewise completely redo the leaves and get them into some nicer shapes and forms as @Manupix was saying as well.
I did a version where I replaced that messy red/brown on the clothing with a more "witchy" dark blue on for the hat and top and boots. Not sure which works more, my instincts tell me the blue brings a bit more vibrancy but what colour balancing I did was done with the green and red/brown so maybe I should stick with that.
I also added some yellow/blue into the hair. The hair in question is meant to be pretty much a white blond but I was hoping to work both blue and yellow into the shading, (a little simular to nia's hair in ttgl)

Drop shadows haven't made it onto the pig yet. They looked nice but i'm considering how complex I want the shading to be. I'll get back to this with a verdict.
My colour pallet is still a little weaker then yours, and maybe i'm a being a little to timid, but i'm still a lot happier with the picture over all. I'll re-approach it in a week, any further suggestions on what i've done so far would of course be welcome.
Oh and thanks everyone for the nice comments.
