I started doing these during the pandemic, if not the first to do GIANT TMNT certainly one of the very first.  I've built a substantial following on Instagram showing off these beauties.  I occasionally take on commision work of making a giant version of peoples favorite figures.  But a lot of time goes into them prices range anywhere from  $500-$3,000 depending how big, does it have accessories. ETC, does it involve making a 3d file from sratch / high quality scan, then digital clean up, articulation, printing coating in a 2 part epoxy to cover layer lines, sanding, priming and painting.  The production for one can easily take a month or so for me to make one.  I have worked with people through payments, showing progress throughout the process but the Giant figure will not be shipped until the full balance has been paid.
