There's a lot to browse there, so I'll suggest a couple of things.
Have you considered braids? Just a French or Dutch braid can make a difference. Or you can try something simple, but different like a fishtail braid.
(Most of those ladies on YouTube have tutorials for those three types of braids.)
If you'd like a completely different approach, you could curl your hair. I don't know does your hair hold curl, but it would be interesting if you'd like to have it down for the photo. There are many heat free methods for curling hair, but then you'd have to experiment to see which one will work for your hair.
What works for me is this fail-proof thing:
- NW/SO on the scalp, with periodical length
washes (Alverde birke-salbei shampoo for the length)
- brushing, scritching, preening and massaging daily
- occasional S&D trims
- trimming the ends whenever they start looking funny
