hey steph,For Jorinda I like #4 the most, it really jumped out at me. #6 is also pretty. Did you look at some reference for bird colorations? Maybe that could be good inspiration and help allude to her fate. For Joringel I like #5, but his pose looks really off balance. I think you could play with the witch a bit more. They colors you have used are essentially gray, and you can get away with a lot for her. Maybe experiment with some dark darks.
I agree with Liz on the 5th Joringel. As for the witch, I like the 4th one.
