What does this look like to you?

Hi guys. First homebrew batch for me.
3GAL Duvel clone recipe, with White labs Belgian Strong Ale (PP).

This is day 4 of primary. Temp should ideally be 82F but climate here only allows me to go as high as 68F. Ive read a lotta threads but never seen threads talking about krausen that looks like this. Thing is Ive been very thorough with sanitizing everything before and during use but I have no gravity-reading or temperature-controlling equipment, only beginner tools... Also the Krausen was never thicker than 1/2 inch and airlock activity was always meh. should I be worried?

Thanks a lot

Some times the krausen falls and you never see it. Some times it hang on the surface and might need the fermenter to be jostled to get it to fall. Yours looks like the latter and it is just fine. Give it some more time and it may fall on its own.
