Create finished app demonstration/presentation Photoshop images

Hello, I need to produce (Photoshop made) app presentation images, that demonstrate the apps functions in actuality. I have already had some images made by another app presentation image designer (Image 1). However, there are 3 produced app function presentation images from the bunch that I'm not happy with (Image 2, Image 3, Image 4). I want these images to look more professional. They need to look like they are showing an 'augmented reality' ([login to view URL]) image (if someone has prior knowledge of working with Photoshop to produce 'augmented reality' type images before, that will be a bonus). They need to produce arrows and icons (+ a navigation map, at the top left-hand corner) in a similar fashion as shown in my app product concept images, 'Image 5', 'Image 6' (in these images, the arrows are the same color, and need to appear as if actually are against the floor [NOTE: the text in the left pointing arrow says 'Science section', the text in the right pointing arrow says 'History section' and the text in the forward pointing arrow says 'Reading areas'. The text in the arrow of 'Image 6' says 'Napoleonic Wars'. The map can be made in enough detail as to seem as something you would see in an actual app) and 'Image 7' (the arrow needs to look like an 'augmented reality' looking floating arrow, the book needs to look slightly highlighted in red, the information box needs to look like it's popping out of the book in similar way as shown in 'Image 7' [you can choose how the information is layout, so long as it looks like you would see in an 'augmented reality' image, and it looks professional so nothing too flashy]). Needs to have a presentation similar to 'Image 1', 'Image 2', 'Image 3' ect., but better looking. If accept your offer, I'll send over the .psd file images of 'Image 2', 'Image 3', 'Image 4' (as the previous designer left them) and you can get to work on them with Photoshop.
