hi indeed the main problem is that the logo is too detailed as they are considering in very small size here … the second issue is about lines which , for the same reason seem a bit too thin, too … i am not sure if the concept has a real commercial potential so i will not comment much about it apart from saying that at least u tried to bring originality … otherwise the typo is flat , this is lacking creativity and originality as well as this is lacking variations and font combinations indeed. Also beware the contrast issue , some of your text or elements are not always super visible or readable out of lack of contrast
