I would like to share some of my Graphic Designs Tips:
1. Vague/Busy- Make sure that you are projecting all you need but do not abuse. Some content can be inferred. Keep it simple but informative.
2. Contrast/Legibility- Make sure that you have a good contrast between your focal point and the background or letter. Other wise, it will be very hard to understant. Our current mode in fonts are the Bold ones.
3. Beauty/Relativity- There's no standards for Beauty because this is part of relativity. However, there are some features that can catch the human eyes attention. For example: Use a significant size compared to the negative space in the art board and use a palette that contains harmony within the colors.
