It does not look right

Question

Someone asks you what you think of something and you want to say "It does not look right"

Answer 1

1. No me parece correcto.
2. Me parece que no está bien.

Answer 2

Context provides different options. Toni provided a couple of good ones.

Also if you're being asked about how something looks (say, a paint job), you may anwer: "No se ve bien" (Literally "it does not look right")

Now, if someone tells you something and asks what you think about it, you may answer: "No me suena bien". - "Doesn't sound right".
