Research - Possible Fairy Tale Choices Brainstorm

I have made a list of fairy tales and folklores that I know of. (see above)
(For clearer image of mindmap, click here)
Now I'll have to choose one of them for the final product to illustrate the book cover for.

I have sorted the fairy tales into two groups: Princesses (romance) and Adventures (non-romance) for easier organisation.
Since my end-users would be kids and gender is not included, I think the Adventures section is more universal (since some boys don't like stories about princesses).
That leaves me with the choices of: Aladdin and the Wonderful Lamp, Little Red Riding Hood, Alice in Wonderland, Pinocchio, Goldilocks and the Three Bears, Ugly Duckling, and Hansel and Gretel.

Aladdin and the Wonderful Lamp:
I think this story is a good choice since there is a lot to illustrate and is challenging too. If I choose this story, I could play around with the colour tones and glowing effect of the magic lamp.
Key objects: Aladdin, flying carpet, Arabian night scene, treasures, genie, magic lamp

Little Red Riding Hood:
This story might not be as challenging to draw but it could look really nice if done properly. The contrast between the woods and her red hood is vivid. Also, the forest could create a mysterious atmosphere.
Key objects: Red hood, forest, big bad wolf

Alice in Wonderland:
This story is challenging, and very rich in contents and colours. There are many ways to illustrate this story with different atmosphere such as mysterious, curious, strange etc. It is one of the most fantastic stories in the list as well, which may be more interesting to children.
Key objects: Alice, rabbit in waistcoat, Mad Hatter, Cheshire Cat, Queen of Hearts, cards.

Pinocchio:
This story is quite challenging as Pinocchio is made out of blocks of wood (which is hard to draw) but there is not as much content to draw about.
Key objects: Pinocchio, Geppetto, sea, whale, sailing

Goldilocks and the Three Bears:
It is not very hard to illustrate this because of its simple contents, although it might make some work to make the bears look animated and friendly for children book.
Key objects: Goldilocks, three bears, bears' house, soup, forest.

Ugly Duckling:
This story is simple, but it would take a lot of work to make the duckling look cute and feathery in a way and animated as well. This story would not be as difficult to illustrate but it lacks adventure and rich atmosphere in a way.
Key objects: Duckling, mother duck, sibling ducks, pond

Hansel and Gretel:
This story is challenging when it comes to drawing the details because of the candy house and it also allows different ways of expressing the sinister atmosphere of the house in contrary of its cute appearance.
Key objects: Hansel, Gretel, candy house, witch, snowing forest

Conclusion:
For the final product in Personal Project, I decide to do Alice in Wonderland:

• Challenging
• Full of atmosphere
• Flexible and creative character designs
• Popular fairy tale for children
• Personal favorite
