I think it looks super! I see a difference The color IS gorgeous, wow. You've got a lot of natural color depth, and it really makes your eyes stand out as a striking feature. Not sure about making your hair look more thin, but I do think adding in highlights would soften your overall look, give you less contrast, if that's something you were interested in.
As a fellow owner of fine, thin curls I hear you on the scalp-peek woes; pretty much all of my hair time each morning is spent on putting in the volume I've slept out and trying to get the crown hair to spread back out again. I have found that getting more regular haircuts helps a lot with managing this. Since this type of hair is so sensitive to weight, having the layers at the right lengths produces much lighter and bouncier curls. I'm actually going in today myself, debating keeping up my angled bob or going for something different. All the good curly inspiration photos are of gals with such thick hair it's hard to find a cut that'll work on my thin hair -_-
