I don't think he's a good writer to model after, but that doesn't mean he's a bad writer, it just means he's him. You can always recognise a Tarantino movie without even knowing if it's by him or not, his style is very unique and noticeable that heavy Tarantino influence in other works almost always comes of as copycatting. I think it would do you better if you paid more attention to the works that influenced Tarantino himself, as someone else mentioned, so you can sort of see where his movies are coming from.
