I would like to explain why I chose large fonts for the whole book title. The maximum thumbnail dimension in the kindle book listings is 115*115px. lf I had chosen to differentiate them with a smaller sub-heading it would need the html code title provided by amazon to the right of the thumbnail to complete the title. Strictly for eBook publications it can be enough to focus on convincing key visuals since the rest is duplicated by the site.
Thank you all. I like elements of each. Please focus on conveying (1) a young adult, (2) a overwhelming burden being borne, and (3) the second half of the title presented in a dark or ominous manner. Thanks!
The design is a draft, if it something you like I can build upon it more. I will add natural lighting, create a natural depth of vision, work with colors etc. If this concept is something you would consider paying for then it is worth my time to continue the work. So please let me know.
