WIP mini diorama : 1/144 EFGF M61A5 Main Battle Tank part 1

I build this mini diorama for my entry in Imoutou HGUC group build 
at first I want to build this battle diorama, with a couple of 1/144 EFGF M61A5 "Semovente" Main Battle Tanks and Zaku 2 from the HGUC hardgraph series I bought before, but because of my busy schedule lately,
I must change it to a simple mini diorama that consist of only a 1/144 EFGF M61A5 Semovente Main Battle Tank :p


First of all I get rid of the extra part that usually added to prevent the small part from breaking
like this rifle

and then fill in the hollow part with Tamiya epoxy putty

and then add up a little detail on the tank

 

 

 
after that painful works with these small parts, I start to add the Tamiya Fine primer surface

And also I make this mini diorama with gypsum, make some tank trail on the diorama while the gypsum casting is still not cured.
  

After 2 days I start to add some colors to the diorama
I spray it first with a couple Tamiya Flat Aclyric paints

then add up some greenery and finiish it with some Tamiya Enamel to make the wet surface effect
and this are not suppose to be grass, just some mosses or green thing that there on a damp and humid surface

 Then I start doing it with the tank too with a couple Enamel paints on it

I still didn't add some washing, and detail painting on the tanks, also the figure that pop out of the upper hatch (sorry I'm not a military kit modeler so I didn't know anything about tanks)
And this is the result for the moment

Need some advice on it, Hope I can finnish this kit in time :)
