bit of editing in paint.net - adding arrows and such - but the rest was in blender.
If your try to go for the blue print look, then make the blue a lot less saturated and a bit darker. Also make the outline less heavier with a very light shade of grey
Decent model 
Well I would personally give you points for being unusual in your project decision, the way this is presented is quite different from the usual work seen in this forum.
But as said before, maybe a less saturated blue would look better, you could also perhaps add lines for measurements to go on as well as for organization purposes so we better know which of the text goes with which of the diagrams.
