First of all, nice job! I really like the content/story on the mainpage. You are a good writer and it invites to read along/stay put for what more is coming in the future.
I will try to give you some pointers!
I would tone the colors down abit indeed.
It doesnt have to be lifeless though. The colors are just abit strong, i would opt for a more neutral colorscheme.
The different 'parts' of the site, on the left the sections recommend reading/categories etcetera, dont really integrate well, and i think that is because of the thick black lining around the different sections.
On the other hand, a site is partly about personal style as well so if it works for you i would stick with it
