>>9350028Yeah but what about Okawara's designs do you like? See, the thing is that almost all the gunpla kits in the last 20 years have their proportions and aesthetics reworked by the younger mecha designers (Katoki, Ebikawa, NAOKI, etc), so if you're after Okawara's stout and tank-like aesthetics specifically then it's hard to find that among the Gunpla, even when it's a kit based on his designs.
If you just like their simplicity regardless of aesthetics then to answer
>>9349996 you could probably find some IBO or AGE designs you'd like.
