Uhmmm... no...
As of now, the suspension, with these octagonal "wheels" - and corresponding track that "breaks" neatly at 45 degree - looks like taken straight from "The Flintstones". Also, the track at it's upper run should go (from the front to the rear): horizontal > slightly downwards > more heavily downwards, and here it's: horizontal > heavily downwards for a short while > horizontal.
Also, another small problem might be that it's NOT Krupp Leichttraktor, but Rheinmetall Leichttraktor:
And finally, You seem to have made a drawing of the opposite side of the vehicle, that had big exhaust pipe on the right side, which is completely missing from Your drawing.
