Very cool that you creating these theme dio's..its awesome for display.

Thank you, I create them for my toy photography. I'll probably end up using this more for Usagi than anyone lol

I think this is a great start. It looks a bit bright and clean, I imagine shredders dojo to be kinda weathered, dark, and a bit dirty. I also think some wall scrolls with Japanese characters and maybe some dragons would be a nice accent. Weapon racks made from chop sticks would be nice too. I've never made a dio, but opening it up with some kinda of arched entryways on each side would be cool, they could even be boxed in on the other side to keep you from seeing out, and maybe a drape so you could adjust how open the entryways are. Wow, that's a lot of text... I hope the constructive crit is well received because I see huge potential in this.

I plan on making some scrolls tomorrow and I wanna get some weapon racks actually
