I'm working on my Heng Long T-34. Here is some progress:

I am going to add two large louvers under the panel as this is what you see on original tanks.

That's really starting to look good. Can't wait to see the finished product.

I added the louvers made out of styrene.




I've painted them green so now you can hardly see them. But I wanted the suggestion of "something there" in case you could see through the screen in the right light.

It looks good, the detail under the mesh adds quite a bit of much needed depth.
