If it was me I'd do one page on booleans. Show a picture of what the wire mesh looks like. I'd probibly do two more pages on texturing showing how it was done and pictures of the material library showing the settings. The lighting. You never showed a screen shot anywhere of where they are sitting, why you put them there or anything. Show a picture of just that and screen shots of the lighting settings. This is where people will have problems. Just look around here and see all the questions people ask about those topics. If you fix those areas almost everyone will be able to attempt this project and that's what you want. Right? Like this tutorial is like 4 in one and you only explained one. Now you don't have to go into great detail with the other 3 topics but you have to at least give some detail even links to more tutorials for further reading would work. You can also fix it really easy by adding about 5 more pages.
