Turtle by Kamiya Satoshi

[kentookura]

Hi, everyone.
Kamiya recently posted the crease pattern for his turtle.
I am having trouble correctly collapsing the leg/foot area, it just doesn't lie flat.
Any Help?
Crease Pattern

Thanks in Advance

use the folds above the feet that look like sinks to flatten the base.

Is the reference diagonally 1/3 from the start of the shell patterns?

The reference is pretty easy. I found by printing the crease pattern and playing around.
I dont know the reference specifically, but it is somewhat based on 2nds, 4ths and 8ths, rather simple.
