NICE build! Looks quite interesting and the paint job is a pleasing and authentic-looking scheme. The Tamiya kit of this vehicle - the first release thereof, way back ca 1970 - was my first ever 1/35 armor build, followed by its tank brother (also Tamiya kit)! I still have the tank, but the semo vanished into some move or something way back

Nice to see this rather old subject bouncing around in new builds!

Your iteration of these old ladies looks superb in most respects!
The tracks are much better when done in links - any links, metal or resin or even styrene (if there are any) - than the kit rubberbands (ugh

). You added a lot by adding those Fruilies!
A couple of things: Yeah, as noted by others, the kit sandbags are, well, "off"! Actually, they look almost like over-full grain sacks! Maybe what a bag of popcorn would look like!

IF you replace them with almost anything looking more like a heavy, saggy, form-fitting bag of sand, it would make a LOT of difference to your otherwise nice presentation!
This being the "constructive feedback forum": The BIGGEST "gaff" (and I'll not mince words, here) I see here is on those suspension unit (bogies?) springs... They are, alas, highly visible on this vehicle and in your build - and you left the very visible (and admittedly hard to remove, but...) mold-seams on those spring-leaves. Almost nothing in an armor build leaves it looking more like a "model" than these seams. (BTY, yes, it IS hard to really get those cleaned up, and much more so when on the build... seam / mold lines are the bane of plastic modelling, IMHO! But they are kind of OK when on the rubber ires, as we've learned that the real tires of many vehicles actually did have seams around them. BUT NEVER flat rolled-steel spring leaves!). You may be able to hide this by applying some mud and dirt build-up on the top surfaces of those springs?
That little detail aside, I think your semo is super-cool and makes me once again think about getting one and seeing what it is like as a build project!
Thank You! for sharing this!
