hi this is sort of fair but to be honest i agree with my friend @DesignSomething . The fact of the matter s that , apart form a few “mistakes” this is clean but also not bringing anything really new to the table in the meanwhile , too, if u ask me … Apart from the “new” or creativity issue, the main problem that u have here is about colors and contrast , if u ask me … the grey / black is not a super good idea with the dark blue color. The other part of the issue is also that your text on the mid range blue is not contrasting enough, i would not go as far as saying that u are violating the contrast basic design principle but this is also true that the text are not popping out as expected and they are very far from being super readable . The solution might be to rework colors a bit or to try to bring some boldness to the table and re-arrange the other text to keep the hierarchy rolling. Indeed, writing over a picture or a shape is not the best idea that u may have since this is making text hard to read and this is hard to determine a single color adapting to the background behind so that the text is hard to read and what is the point about putting a text if this cannot be read? The disposition is not purely timed as well, as u may or may not know the z-shape reading process, in other words, the way the eyes sweep across any document is not only determining the impact way it makes sense to organize elements , but also determines the impact zone as well … the good positioning for a logo is either the top left corner, the botton right one or the very center of the page …
hope i could help u
