Well you’re doing great first of all with a nice clear niche focus which other people are likely to have a passion for and search for. I’d look for any other blogs or forums on the subject and engage with those too, using your blog as a place to talk about what you find or publish useful information for and from those sites.

You need to publish regularly about your subject – even simple links can get you in a good habit and you can build from there. The one post so far is about you, not the subject, and that should probably go on a separate ‘About’ page. You should also take your mobile number off. More generally, edit your work as tightly as you can to remove typos, grammatical errors, etc.
