I'd give myself, like, a 3.5??? I've been told my art looks good, but I still see a lot of room for improvement, haha, and I'd honestly argue that if a 5 is anything near perfection there are a scarce few humans out there that could even hope to get anywhere near that.
With that said, a lot of you guys are severely low-balling yourself. Your art looks good, have some faith. : )
