Phew, finally done! This was my very first time drawing/shading in GIMP, so it's far from perfect. Comment what you think, so that I can improve! Also, if you have any requests for more designs let me know!
I love what you did with snow whites!!!!! And how you made belles long because she wouldn't wear a long dress. But I don't like jasmines colour, she's more of a blue. I love how you did auroras, really keeping the main features, brilliant! I have never been keen on Cinderella, so don't take it the wrong way but I don't like it, I never have. Aries is also excellent, it reminds me of tinker bell a little but it really suits her.
On the whole it's fantastic, just some of it is not to my taste.
I like the designs! One of Ariel's main colors is purple, so maybe you could've put that in her gown to make it look different from Jasmine's. Also, maybe you could've darkened Snow White's bodice or lightened Cinderella's dress to make them unique from each other, too. But I like Aurora's gown a lot-the fishnet is cool. The stripes on Jasmine's are nice, and I like Belle's gown.
I really likes belles simple design with just a long gown and some roses there at the top. If it had been in another color (say... red, blue, green or purple) I would have wanted it right away. But then it wouldn' be as Belle as it is now, since Belles gown is yellow.
I think they look rather good for your first time using GIMP =]. Drawing, coloring and shading just takes practice on GIMP. I use a computer mouse to do mine so it takes a bit more practice Take a look at one of my GIMP airbrushes: [link] But like a said, very good for your first use of drawing/shading
