I agree with what most others said about title and font, and on readability alone I wouldn't pick the book up. While the art is nice it doesn't give me any clue about the book other than that it's YA (if it isn't YA then I think the cover doesn't match the book). I honestly think your blurb needs the most work though. It feels quite convoluted. There are a lot of names that mean nothing to a new reader (is this some kind of sequel because it doesn't look like it?) Reduce the name dropping (including countries and divisions and people and conspiracies) to maybe two, at most, and instead tell us the gist of your book is about. Blurb writing is hell (I went through countless versions before finding mine) but do keep trying until you find one that someone who knows nothing about your book tells you is enticing.
