Reddit reviews The Secret of Orchard Cottage: The feel-good number one bestseller

That's better. The author name definitely looks better at the bottom. I'd have a different typeface for your author name and title though. Something a bit more bold for the title. Also, try a different layout, maybe 'There's' on it's own line, smaller than the rest which is centred. And maybe try playing with different fonts within the title, and colour too.

By strapline, I mean something like a subtitle, or a simple descriptive sentence.

Quickly going through the bestseller list:

• The Racketeer by John Grisham - He was betrayed by the FBI. Now he wants revenge.
  
• Sleep Tight by Rachel Abbott - When obsession takes over
  
• Behind Closed Doors by B A Paris - The perfect marriage, or the perfect lie?
  
  Or even a pull-quote from a good review:
  
  
• The Secret of Orchard Cottage by Alex Brown - As sweet and charming as homemade apple pie.
  
  I tell you what, here's a quick and dirty example of what I mean.
  
  It's by no means perfect, it's just to give you an idea of what you could do with a little typography to make it look a bit more professional. I also made the illustration smaller which will give you more space around the edges. Don't be afraid of space.
