So much awesomeness!!!
I really like this character!
I agree with a lot been said here already, here is my two cents
I did a paint-over using the first cover idea, increased the size of the character, updated the contrast of the character and background, added water splash on the character to help the character silhouette stand out more and have better readability from a distance, some atmospheric perspective to separate the front leaves from the hill and character
mess around with the title changing color and adding stroke lines
I hope this helps give you more ideas for your cover and finish with a product that both you and your publisher could enjoy.
Thank you!!
