It is 'just a hobby', but I think we must allow for the fact that some figures will produce strong feelings in those who themselves, or whose families and friends, have suffered at the hands of the figure that has been sculpted. We must also allow for the fact that modern sensibilities are different from those in the past, and that the further away we are in time from the figure modelled, the less offensive it may seem.
In ancient times, all civilisations had slaves. The Roman empire was built on slavery, but all Rome's enemies also had slaves. Today we regard slavery as being abhorrent, had we lived two thousand years ago, we may have had different opinions. I remain in two minds over the Templars, who were formidable soldiers, but whose religious fanaticism resulted in what we would today regard as war crimes. To some degree, one man's freedom fighter is another man's terrorist. I think the main difference is that those who fight in uniform for their country against others doing likewise are usually acting honourably. Those who do not, are not.
As for the bust itself, it has been well sculpted and painted, as to whether it catches the spirit of the man, or his suitability as a subject, that has been more than covered by previous planeteers.
