Hi Hilton , could you please pass me some vitamins - I am finding it hard to keep up with your work rate of so many fine models.
I really like what you have done with the Gepard - a simple mono colour base coat - but it has plenty of character
I would go with Greg's suggestion of a bit more metallic wear and tear on the tread faces.
One other suggestion/observation - The gun barrel seems to be painted dunkelgelb - do you have a photo of such a thing?
As far as I know those Flak barrels were dark blue / black , the dunkelgelb would not last long when the gun was fired due to the heat generated and would quickly peel off.
Very nice work again - a nice treat for the eyes
