Let's say you're at the barber shop and he's using his mirror to show you how your hair looks like after he's done cutting it, what would be the appropriate and natural way to say "It looks good (thank you)"?
It's really up to your flavor or your cup of tea. According to your words: It looks good (this sounds you are not going to compliment or denounce him.)
- こんな/いい 感じ
- バッチリです (I have no idea where this word came from, but it means 'perfect')
上出来/上等 (Compare to my face, haircut is way too good, a little humble)
These are appropriate for a normal and casual relation with the barber.
