Evaluating my SFX makeup

I think I placed the blood on well because it's not in one big blob, it's all separated and it looks like the blood has sprayed out of the wound.

I think the most challenging part of the SFX makeup was applying the wax because it would stick to my fingers and that made it harder to apply on the arm.

My weakest area was spreading the wax because 
it's hard to make it blend in with the skin tone of 
your arm.

I need to improve making the cut look more realistic.

To make it more realistic I would make the cut smaller and thinner but use more of the black paint to make the wound look deeper.
