Sorry to say, but Shipbucket-wise she's
not looking good.
First of all, unless it's resized (and judging from the scale bar and caption, it's not), then You've got a HUGE problem with artifacts.
Secondly, by convention, wings, horizontal stabilizers, struts and the like have to be - with exception of their ends where they are thinnest - at least 3-pixel thick (or more, if necessary): black contour - color - black contour.
Also, if that grey tear-shaped thing on the fuselage, below the wing, is a float, then it needs to be outlined in black too, as now it's just something painted on, not a physical entity.
Here are few examples of the drawings of aircraft of generally similar configuration and era (sorry for such shameless promotion of my own work, but it just so happens that majority of WW1-era aircraft drawings were done partially or wholly by me)
