Thriller Planning: Raw Footage - what to improve

We went to the abandoned house to do some practice filming, and found that a lot of the raw footage needed to be improved.
The first shot was too long, and was not close up enough. It meant that it did not create tension and suspense for the audience.
I thought the second shot was quite effective, however it could be improved by being more of an extreme close up. This would have obscured more of the surroundings which would create more tension.
The third shot was also much too long and did not quite work how I expected, but with more practice I feel it could be quite effective. The way it is slightly tilted gives an impression of vulnerability and confusion, and the panning works well, but the shot is too long and the character moves too far away for it to work well.
I liked the fourth shot but, again, it was not close up enough, which did not create enough tension to make it effective.
I thought the fifth shot worked really well. The exaggerated tilt emphasises the vulnerability and fear of the character. It could be a little bit closer to make it more effective, but overall I think this shot was good, and so could be used again in the real filming.
The point of view shots did not work at all in this shoot, however I feel they could be better with more practice.
The revealing of the body was made too obvious in this sequence. It needs to be made more subtle, for example only seeing the feet or the arms.
