This is a good rendition. May I suggest that for the rear engine exhaust you use the grey chunky space tyre, it's exactly like the reference pic. There is also another winscreen style more suited as seen on comparrison MOC. I agree with Firas about the dispersal explosives thingys otherwise well done.
That's a great replica to the one in the picture! I couldn't find any thing to improve except the dispersal explosives things, everything else is just so accurate, if there's a voting or something like that I'd vote for yours, keep it up pal >>> peace.. Firas :)
