eBook Conversion Rate

I wanted to show everyone this because this is a really high conversion rate, it boosts my confidence, motivates me to keep writing, and makes me pretty darn proud. This is Smashwords, not Amazon. Amazon doesn't show me how many people have downloaded the sample. I was told to expect 1000 sample downloads to a sale so this is pretty awesome.

Struggles with my new Cover

Since publishing "Be Careful What you Wish For" I've been working on a 3 book series called "Witch Slave".  The fist part of the series is ready to publish but I'm struggling with the cover.  I've found part of the cover I want which is the silhouette of a naked woman against a fiery orange background but I need a blue or blue violet fantasy background with a ragged, scary looking, ship with massive sails, and a jupiter type planet in a starry sky.  I can't find the second half I'm looking for.  On tip of that I'm also have a hard time getting those two pictures to blend together.  I want the orange photo with the naked woman's silhouette on the bottom and I want it to fade into the blue violet picture of a haunted ship and a fantasy sky on the top.
