Newbie would love some tips!

Hi friends :slight_smile: I’m a new newbie! This is my 3rd project. It is a social project to help with the housing crisis: It combines people who are looking for a home, with people who wants to share their own rent.
As a newbie, I am not happy with the colours, how to use them, I don’t know if this isn’t too much blue.
I’m not happy with the logo I have created either, I’m not sure about the concept…
I’m really really unsure. I’m looking to my job and all I see is a children work, and I spend a lot of hours with it :frowning: its frustrating really :frowning:
Can you give me some tips?
