Did you make models as a kid? I did. Plastic cement and messy decals were a weekly duo on my kitchen table. I got better as I got older, but even by the time I stopped (at around 14), I could only dream of putting together kits like this.
This is the work of Japanese modeller mdsm, who while specialising in Maschinen Krieger also does some fantastic work on stuff like Gundam.
While his paintjobs do a lot of the heavy-lifting, its his customisation work that really makes this fantastic, from the celebrity homages to the scratch-built characters to the little tweaks he makes to existing kits that make them a little more "his".
