how should a throat of a singer look like? will there be lumpy , tissue like muscles or surface?

Answer 1

Watch all of the singing reality shows. That should give you some in site.

Consider your age, the amount of vocal lessons you have had.
How much you practice. I would think your vocal range might
have some effect on how the throat looks. If you truly want to be a singer, vocal lessons with a good coach and practice, practice, practice.

Good habits versus bad habits would effect the appearance.
