I kinda like how she looks as sleek as a warship. I do get the feeling, however, that she actually lacks some hull depth given her size.
On the aesthetical point of view I would open up the promenade deck towards the stern like it is at midship and leave the windows only on the forward third.
Finally, one last observation: Is the "Height: 27 ft 11 in (8.51 m) " figure intended to be the height of the boat deck above the waterline or the draft of the hull below the waterline? Because in the first case, on the drawing itself, it is 6 pixels higher, in the second case it is 10 pixels too shallow. (increasing the latter would mostly solve the "too thin" feeling about her)
Take it as a constructive criticism to improve your ship.
for example the liner you have in the previous page looks really good.
