In the beginning I found Hive was all about getting out there and engaging.
Just because you have written a post don't expect anyone to read it or leave a meaningful comment. I wrote hundreds of comments and tried to find people that I enjoyed reading. As long as it is fun then it is enjoyable and with that comes growth.
Progress updates are great, there are some great sites and tools. I do like reading hivebuzz.me for example when looking at the stats.

You can see I rank 136th out of all Hive accounts for comments made. Almost 50k in three years!

Just have fun, keep it original as you are doing, and make sure if you do use images that are not your own, then they are freely available for commercial use.
