final result

well i now added all the props together and now here are images of what the whole scene could look like. The plain image by the way is blood splatter. the splatter look realistic but the colour of the blood i feel needs to be darker.

the gloves

latex gloves for the surgeons hands

knife props

Here are some knife props there are more to be added I think the knife without no handle is very effective as a killing tool.

props for blood

all these items are mixed together to create fake blood its not quite there yet but we will fix it
