"Inconsistency reads as carelessness, even when it wasn't."

Do this now

Pick one element — a typeface, a colour, a spacing unit, a shape. Check every place it appears in your design. If it's slightly different each time, standardise it. Consistency is a decision, not a default.

Unpack

Repetition builds visual systems. When elements repeat consistently, the viewer learns the language of the design quickly. Inconsistency creates low-level visual noise that erodes trust in the design without the viewer knowing why. One clear rule applied consistently is more powerful than ten rules applied loosely.

Draw it.

Fast and messy is better than perfect.
