Is this chart to give to students or is it for you to revise? It's OK for revision although too much simplification can be problematic. There's also a mistake in the past continuous box.
The future is very difficult to simplify because we don't have a proper future tense, we just modify verbs and use other tenses to indicate the future. You might want to break up that section into different ways of talking about the future.
