Try writing 'dad was upstairs working on his computer' rather than 'the computer.' If Mom is in the kitchen working on a computer its a different one than Dad is using.

You portray a child's emotions plausibly, and I like the detail about the spiders webs moving. Perhaps you could've had them find out later if someone died prematurely in the house, or if a previous occupant had a scary experience there.

Not 'too' far away rather than 'not to far away.'

'Blood was seeping into the snow' rather than 'blood was fading into the snow.' It would trickle down rather than turn pale.

Had you described the man flailing trying to retrieve his lost knife before striking back, then the action would've flowed better. You're descriptions of the fight are tense and fast moving, but bear in mind what I've written and you're writing will improve.
