I have no idea. I just get more ink when the cartridge runs out, so I never know how much I spend on ink. sorry. but since it's about 120 pages and mostly dark parts I'd say it's pretty costly.
if you make the small and then the large version you'll feel like thumbelina just because the parts are just blown up! I loved that feeling. but be sure to follow the tips on how to make it sturdy! it's a very wobbly affair if one doesn't make it super strong. all that weight from the head gear and head, on that thin neck... make it strong! my first Midna had a baby neck problem even after I made it stronger, just because the head weighs so much, so I made the other two rock solid.
thank you! I'm not sure how to answer that but I guess she was hard to build. I'd say at least a 7/10 but I can be wrong. some parts was harder than others, like the horrible snakes on her helm! I hated making those stick. I'm not good at glueing large pieces together.
