Create graphics for important slides to help simplify concept concepts. You don't need to make as many here as in your lead magnet, but you should have them on the most important slides or anywhere you are trying to convey a more complex concept.
Graphics should not be confused with memes. They do not need to be fancy. Their purpose is to teach people something. If the graphic doesn't teach people something, it is not a good graphic. Graphics should be able to standalone with no explanation required. If I cannot look at it and immediately understand it without any verbal or written explanation, it is not good enough.
Design your graphics so they can be read on mobile. If the text or graphic becomes so small that you cannot read or understand what it says, it is useless. Keep this in mind from the moment you begin so you don't waste hours and hours fixing it after.
