Do you have any tips for drawing pretty eyebrows?

I wonder why I always end up looking like Shin-chan whenever I draw my eyebrows...

If I make it thin, it feels like something is missing.

It's difficult because I've never properly trimmed my eyebrows before.

Is there a specific tip for drawing it nicely?

I'm curious if it's a good product or something...
