cover for a middle grade horror book

I'm looking for an illustrative cover for my middle-grade horror book. I have a clear idea of the elements and themes I want included and want the cover to have a dark and mysterious mood. The illustrative cover should be artistic and visually striking, with just the right amount of suspense. This book is aimed at younger readers, so it needs to be engaging in a way that will attract the attention of young readers, while still having a slightly eerie feel. The illustrative cover should be memorable and capture the suspenseful tone of the book.
