I'm still very confused about adjectives and adverbs

[Hugo_Lin]

Last time I posted a question about when to use adjectives and when to use adverbs after verbs.

But I'm still confused about examples such as:

It looks good to me.
It sounds perfect.
It feels good.

why not use:

It looks well to me.
It sounds perfectly.
It feels well.
what's the difference?
