I just visited your IG page. I like the color scheme and consistency with the posts. However, as someone with almost 70K followers on IG, I can tell you that people click on posts with larger letters. This doesn't have to be the case with all posts, but it helps to mix it up.
After your following reaches about 300 people, then your posts will be eligible to hit the explore page. You want people to be able to read your posts without actually having to click on them. If a post catches their attention, they will go to your page and check other posts.
I like that you are targeting specific niches/ clients with your posts and hashtags. To grow your following quickly, comment on large accounts that your clients follow.
Hope this helps.
