@alexisartxox Both look great, but the pumpkin one is so dark and some areas lack contrast and are hard to make out. For picture books, lighter images are a safer choice - while dark images are okay, it's a thin line to walk to still make them easy to make out and children friendly. Very often, these night time images have bright light sources that illuminate a large portion of the illustration, so they are actually quite light and the night time is implied or simulated. Hyper bright moonlight and blue filter anyone?
Your fairy illustration is gorgeous and easy to love, which I think is a safer choice!
I'm not sure about the font choices. The font for your name especially feels a bit amateur, and the text layout on the back feels odd. There's more space between Alexis and Eastburn, than between your name and the tagline.
I'd definitely reduce the line spacing in you name and change the font, maybe for something that looks more handwritten. And a bit of space between the title art (your name) and the tagline!
