Milla Krokodilla

Hi!
I'm working on a little present for a little girl named Milla. She is fond of crocodiles and the name of the work will be 'Milla Krokodilla' (Dutch). I'm going to make a book cover in this course.
1: Finding inspiration
- Direction: book cover
- animal: crocodile
My moodboard:
the color palette!
typography
Use of geometric figures.
the swamp (plants)
2: Brainstorm: warm-up exercise
Need to make some more 'font'-sketches. :-) But I know i want the name Milla curley, gentile and cute and the word Krokodilla straight, big, bold.
Also need to work on some illustrative font!
3: Creating thumbnails
I couldn't wait with making thumbnails because i was feeling inspired :-). For this try-out i'm allready in love with number 2 on the first row (2 hearts). Which one is your favorite up to now?

Update (19/05/2015):
Think i should remake the last sketch because the font is lost in the crowded drawing...
Update 08/06/2015: I combined my first (favourite) and second drawing and finalised it:
I just want to start reading the book! :-) Any feedback before finalising it with color? (I'm going to color it with another course from Mary Kate, namely The Final Steps of Hand-Lettering: Color & Texture (Lettering II).. Excited!
