Ugh, I create long post, added photos and it disappeared 😭. So, my main strategy is colour aesthetic. On both - my portfolio and my beauty IG I like to keep colour theme.
I live in a small flat with old furniture, what I do is taking photos in natural light even if in the winter sometimes it's hard to take photos since we have no light after 2pm. I barely ever use fake light. My main concept is that everything can be a prop in a photography. For backgrounds - I use some fabrics but also paper, old wrapping paper, special backgrounds, what even I can use and afford.
What I recommend to get inspired - create a mood board, I use Pinterest to get inspired but I also like to go to Park. In general, I hope it'll be visible on photos that I like to create an entire scenery. I sketch sceneries and ideas before I make them alive, it's like storyboarding in video making. I also recommend analysing photos, paintings and movies - it can help a lot if you want to go for creative side of photography
