Ok, a few things to an otherwise promising beginning:
Firstly, there's nothing such as 'Her Majesty's
Victorian Ship'! The term
'Victorian' was coined after the death of Quenn-Empress Victoria, in 1901, to denote the uniqueness and particular character of her long, 63 year reign. So, in other words, it's
H. M. S. or simply HMS (without dashes in between!) - but not
HMVS! The only other viable designations were
HMY (Her/His Majesty's Yacht) or
HMAC (His/Her Majesty's Auxilliary Cruiser). The civilian equivalent is
RMS (Royal Mail Steamer; today largely redundant - I'm not even sure the new Queen Mary 2 carries it!) Also the font chosen ought to be Arial 14pts, though for sub-description you may use Arial 12pts in order to differentiate that from your main header.
Secondly, unless an AU-project, IRL we wouldn't describe a particular section or part of an Empire as the main 'owner' such as you've done (Colony of Victoria; btw it's Victoria, you misspelled it unfortunately...) but rather as
Great Britain: HMS Cerberus (1871) - after that you may more closely define to which part it actually belongs, and I'd suggest you'd do it like this for clarity's sake:
Crown Colony of Australia; Colony of Victoria. I'm well aware of
Cerberus's checkered history and that she and her sister were intended for the Australian waters.
Thirdly, since, with the minor exception of my above points have progressed really well and show very good promise in completion of this interesting vessel, why not go full out and make the underwater hull? Now, I own Dr Parke's excellent book on British battleships, and I believe I could help you with the outline of that section of the ship, if you cannot find it otherwise.
Else a very good start, mate! Welcome aboard and kep up the good drawing!
