A logo isn’t just a nice-looking symbol; it’s supposed to represent the organization. Without knowing more about the organization it’s for, what it does, its culture, its goals, the target audience, its competitors, and more, there’s really no way to properly judge whether a logo will do its job.
I think that you are doing randomly designs, or you want to make something to make a portfolio because you don’t have anything yet, and you are looking for something. Doing random stuff is not helpful, and it is waste of time, look for a product then make a mockup (on paper) then make a prototype. Get some inspiration (look for other designers examples) and focus on one product, then if you want another design follow the steps before I told you, and get inspiration in a new product repeat the same steps as before.
A day as in “a long time” or as in “really fast.”
Kinda like saying, “Look at this house I built in a day.”
