A couple things I noticed if I may chime in. I haven't seen an updated pic of your face on the helmet, but the first one needs much more taken out of the tooth openings. You have done well on your biceps and forearms. I would take more out of the top of the forearm half with the square indent ridge. It will make a little more room and may take a bit off the overall length. As for your shins, you can still take more off the bottom. You can also cut a curve (arch)in both the front and the rear at the seam. The shin cannot fall lower than the point it hits the front top of your boot. Make a curve(arch) at the seam that will allow your shin to stop to a more comfortable height.
Almost no one has ever trimmed out their ears before joining the face with the cap. You need to be certain your face joins with the cap properly before moving on to your ears. The brow trim must be tight across the face. Once the face is attached and the brow is tight and even above the eyes(it doesn't have to be perfectly level, just even and located where you are happy with it) then you move onto the ears. Hopefully the one you have already trimmed still fits.
