3D/4D ultrasound at 30 weeks?

Kellie • First time mommy to a babygirl named Lillie ☺️💕

So me and my boyfriend wanna do another 3D/4D ultrasound and we’re just wondering how good our little one will look at 30 weeks? Should we wait a bit longer or is this a good enough time to see her facial features? If you have any pictures can you post em with how far along you were.. thanks 😊😊
