tintin come on very good does not mean perfect if it were so then Adam would not have sinned.
God rested from His perfect work of creation before the entrance of sin and the fall of mankind. Therefore it was perfect!
Just because somewhere down the road Adam & Eve sinned doesn't mean at that time they weren't perfect. As a matter of fact they were created in God's image after His likeness. This means that they perfectly reflected God's agape love - a love that is not self-seeking.
If one rejects this then Lucifer was not perfect in all his ways before he introduced his love of self (iniquity). But the Bible plainly states that
"You (Lucifer) were perfect in your ways from the day that you were created, till iniquity was found in you." Ez 28:15
