1. The Font isn't well chosen; it could be fitting with certain words, but making the entire thing with the same font has an excessive undertone.
2. The way the typography is set, the "a" is completely lost, and the rest also doesn't line up. It's giving me stress-rashes.
3. The title is completely stuck to the roof, while the author's name sticks to the bottom. As above, so below, one should never place any script too close to the edge, as everything too far up and too far down will "leave the frame" in the eyes of the viewer. You've lost both.
4. The Image itself is nice, but I would have likely color corrected it when setting it with the typography.

5. According to color correction, I also would have maybe added something to the logo itself, because the image is nice, however, the cover seems empty and bland. The Logo in full would add some personality to it.
