First time doing lace work

I’m knitting the Elise scarf by Susanne/Paula Muller on Ravelry with Truboo yarn and it’s so ugly 😫

I’m using size 4 needles even though it feels too loose but that’s what the yarn suggests and I don’t want it super tight, I want it light and loose.

When it rests naturally is super scrunched but I know it will loosen when it’s blocked. However, are my yarn overs too big? Should I knit them tighter? Go down in needle size? Should I be knitting tighter in general for lace? Keep going as is?

Thank you!
