An image for a book cover

I will draw a sketch to give an idea of how the final result needs to look like, improvements and suggestions are of course welcome, but bear in mind i got my own personal preferences i want to stick to. I need the help of someone who will make a better version of my sketch and then apply color the way i describe it. I prefer an anime look-a-like image (basilisk characters look fine, if you need an example), but this specific look isn't absolutely necessary. The most important thing is the final image to look appealing to me. The final image will contain two characters like on a poker card (king or queen for example), a guy's top half on the upper side and a woman's top half on the lower side of the image. I do care about detail, so the clothing will have specific design. The title for the book cover i still got to think about for a bit, it's not's mandatory to add a title yet, but it would be good if you could suggest a writing style for the title. The price i am willing to pay is around 25 to 50 british pounds and i am willing to pay more, quite a bit more, but only as long as i know for sure i will get the image i want.
