I really like various forms of photography like you said
For the longest I was only photographing flowers and things of nature as well as miscellaneous objects around the house
So far I have only been able to do what you said, photographing flowers and small animals around the house, it seems I have to start photographing human objects to be able to add my skills in being a photographer
You can slowly move into that when you're ready. The only interest I had in the beginning with photographing people were of my family so we wouldn't have to pay anyone else lol. Then as time went by my interests started to change and here I am now enjoying a variety :)
