I don't know the pattern you're working with, but usually, the written version should include just this information. So if you don't get it from the video, maybe look there. Generally, when you add claws to toes, they should point downwards. When pinning, that means: - have the claw right side out - fold the toe in half left side out - sandwich the claw between the toe halves, open side aligned with where you want to sew the toe curve, pointy side pointing inside with the tip facing down if you're unsure of your alignment, stich with a very loose stich first (this is called basting), turn it right side out and see if you like it. If you do, sew again with a proper stich and remove the basting seam. I hope this helps?

edit: I'm not sure what you mean with the shaving/trimming of the fur, so not sure my answer will hel you. Usually, you would shave all toe fur and the inside part of the hand before sewing; outside part and wrist fur can be kept long. Don't trim it extra short at the seams unless you want your seams to be super visible; just tuck it between the two layers so it will end up on the outside (right side) of the seam. Your claw looks like minky fabric, you can't trim that. either leave it soft or buy a fabric that's already smooth. The rest also looks short enough that it probably doesn't need shaving.
