Design
You've got a fantastic logo there alongside some interesting typography that I think is very eye catching. Your menu is very small and quite condensed so I would look at making that bigger and more spread out so that the options are more prominent.
The whiteness in the background stands out quite a bit so I would maybe look at perhaps making it a bit more pastoral colourwise.
The widgets on the side work very well with things like your Instagram feed showing there.
I would move your 'follow me on social media' to the top above everything else. People will care more about doing that then clicking on an everything5pounds ad I feel.
Content
I found the blog posts very well written. You use good use of graphics / images in the posts. You could maybe interlink your internal pages a bit more. Generally, in a blog post you want to look for 1-2 internal links and 1-2 external links so Google Spiders the page well.
Everything is very easy to read with good breaks throughout a post. I would look to make use of H1 / H2 lettering at times though so that you can make each section of a blog post a bit more obvious.
Thoughts for the future
You need SSL Cert sorting out so your blog is https - Google will be de-ranking you in search results already and you don't want that.
Your subscribe / Newsletter box literally just says this
I would give some thought over this about making it more appealing. Why subscribe? What sort of content will you be sending etc.
You say you feel you are missing your blogging mojo but you've only been going 3 months so far so you can't expect miracles. It will take 6-8 months for things to really ramp up so just keep doing what you are doing at the moment! Be ALL OVER social media, promote the heck out of your posts, write guest posts for other blogs and everything will come togeather!
