Mock-Ups for Visual Effects

This afternoon I managed to book out the Black Magic Pocket Cinema Camera so I can shoot a range of desired test shots. In preparation, I have created a mock-up for each shot:

For scale, I want to create the illusion of a tiny person walking through grass. I may need to apply theory to make the shot more believable, such as making a small character move quicker. It may also be a good idea to select a relevant costume, such as a fairy or pixie, however this depends on budget.

I took photographs of multiple types of grass from different angles to see which worked best, which was extremely helpful when deciding which to use for my mock-up and will hopefully give me a rough idea of the camera angle and composition when it comes to shooting. When creating the image in Photoshop, I found it a lot more believable if the person was shown to be coming out from behind a blade of grass as opposed to standing in front of it, which appeared to look like a flat image.

I'd like to have a lot of control over the colour shot, so an effect inspired by the film Sin City felt appropriate. Both images were taken from Google images due to time restrictions and lack of props (I will need to find a red hood or coat). This shot should be fairly easy to create as I live directly across the road from a wooded area, which will be an ideal location - especially if I am lucky enough to encounter fog on a day in which I am filming.

For invisible shots I wanted to film the silhouette of a person in motion and then change the sky, however this may be difficult with the incoming winter weather, so stock footage may become necessary. I have managed to create a mock-up using an old photograph I had taken of some trees at dusk, but the sunrise was taken from Google images. I found that I clipped far too much detail from the tree branches, so I'll be careful of this when it comes to editing footage in visual effects software.
