the shin looks pretty close to me in the final pic with the boot, but that is without the shoe in it so might push up your foot a little more and make the gap at your ancle a little larger.
maybe make it ust a tad larger id say maybe an inch or just half an inch its really really close tho if ya feel ya got full motion and if you make it larger you wouldnt then i wouldnt change it
thigh looks spot on
Keep up the awesome work!
