On Kindle I used their Cover creator app and got a different result that you can see here
So I took some time recently and reworked the cover. Here are a few options:
A bit more polished. The transparent gradients look a bit more elegant I think. Now I am starting to wonder on the format and position of the Title and Author name. Here the Title is on Top with Author at the bottom.
Fonts are more consistent. I like the way that “The Mason Chronicles Part I” fits in the Mountains on the right. The only drawback is I am not 100% sure I love the way the gradient looks in a small icon like view. I uploaded it for Smashwords so you can see it here.
