Yeshua may have been a historical figure - the jury is still out if this represents a particular personage or was a conglomeration of several.

That aside, yes, definitely depict in the proper manner - a semitic itinerant preacher from north of Jerusalem.  Not the anglicized version, please.  It was customary for beards and mustaches at the time in the region.  Romans, on the other hand, did not regularly keep facial hair.  An interesting recent documentary about the "Family of Jesus" pointed to the fact that his face was probably not long as regularly depicted (but this is all assumption on local traits two thousand years hence).  I wouldn't use the Shroud of Turin as any reference since its origin has been soundly determined to coincide with its church-denunciation as a fake in the mid-14th century.
