hi in fact that would be easier to tell u what is ok rather than what is not lol it would be faster lol
here are the problems
1- global lack of graphic design
this is too simple, u need to push the envelope graphic design wise
2- choices of colors
everything is quite dull color wise, u should introduce some contrast and make sure that there is some a bit punchy , too
3- hierarchy
as all is really flat , there is naturally nothing outstanding indeed …
4- typo
this is too flat , u need to introduce originality and font combinations, add variations as well so that u build a real hierarchy of information too
5- text arrangement
the block of text on the left side looks messy as such make it a clean block instead , it will look clearer
