Feedback for my wordpress blog...

Hi guys,

I read through a few other posts, and would really love feedback on my WordPress blog myself.
I have been leaing SEO by my self for a while now, however, I am still struggling with my Moz DA score. I've been stuck at 7 for so long, and just when I got happy for getting to 8, it jumped back down. Is there anything I can do website layout/pages or post wise to help me start really growing my score?

My blog is https://www.alexajade.co.uk WordPress ...
