The tank doesn't look bad, but it's also a cost issue in itself. Whether you want a Pro version or the standard version of it, as I also do a lot of conversions on my RC tanks, be it with photo etched parts etc. It would still imitate a rough cast steel structure on a Russian tank as long as you don't have the spare parts on it, that is I would do a lot of filling and sanding on some parts, and highlight a few details.
