I like it quite a bit. Only things that seem off to me is the section headings on the homepage (Our Idea, Recent, etc), and also the search seems to be in a weird location. I would remove it from the header completely, or maybe just add a toggle search in the header.
Edit: Also, I would maybe make the colorful logo smaller or something.. seems a bit odd or too large.
Just my 2 cents though. Good luck!
