Smoothing an Existing image

Hey everyone.

I'm looking for some help with smoothing out a hand drawn image. I have the picture of a tribal tattoo and I'm trying to smooth the edges (they look rough at the minute) so it looks more photoshop-made? But I'm having trouble. Does anyone have any tips?

Without seeing the image I really can't say what you need to do. I'm not even sure I understand the problem.....

Its a hand drawn image.... check
You scanned it.... (assumption).... check
Now you have it in photoshop....check

You want to smooth the lines.... now see here I would want to know about a dozen things about said "lines".

How thick or thin are they?
Are they fuzzy from the scan or are they nice hard lines?
What is the ratio of thick to thin lines in the image?(if they are different sized lines)

The list goes on...

Post the image.... with your name printed across it if need be or if you are worried about someone snatching it, Or you can shoot me an email. (PM me for direct addy)
