MY OPINION ON THE COVER
Well this cover seems to follow the same sort of theme as the cover of Book #1 which keeps things consistent. I suppose if you have read Bk #1 and are looking for Bk#2 on a book shelf it should stand out to you.
Of course the cover shows the outer space theme, and I like the shades of blue used as they make you think of outer space etc.
I also like the byline of Will you fall? on the cover. It is asking you a question and so piques the interest even more.
Other than these comments there isn't much else to say.
