Nice !! I have the virtuso as a commuter and i really like it
You have to be careful with sizing as all manufactureers measure differently and some list the bike with the seatpost lentgh as measured and some list it as where it would meet the top tube if the top tube was not sloping (virtual ).
It is hard to say from the piccie but it does not look far off , without seeing you on the bike we cannot say for sure.
I found a good starting point for seat height is to put your heel on the pedal , your leg should be straight, another way is to multiply you inside leg by .883 , my inside leg is 77.5 x.883 = 68.5 cm ( plus or minus a few mm for comfort ) from centre of the bottom bracket to the top of the saddle.For me i have it up another 3 mm.
Setting how far your saddle is back , most people use KOPS, drop a plumb line from where the bottom of your knee cap is and it should go through the pedal spindle when your foot is at 3 `o clock , i personally have it 1 cm forward , you have to play around with it till you are comfortable as some people prefer it in front or behind.
To get your reach right you can look at the centre of your handle bar where it meets the stem and this should hide the centre of your front wheel, changing stem length affects this .
Drop from saddle to handlebars , this depends on how flexible you are and what sort of riding you want to do, i notice that your saddle is lower than the handle bars but this could be down to getting it set up right.
Some people prefer to have the handlebar level with the seat or lower, generally 2-4 cm lower is the norm or 6cm+ for a full on race machine, mine is set with around 3 cm drop.
These are all just starting points to work from until you get a comfortable fit as everyone is different.
This is how mine looks, bear in mind that it is set for me and you will be different .
