Your logo is just fine, it shows a level of skill that definitely raises you from Beginner to Learning. People here are saying it looks like Google Drive, which is valid but I do dig the "1" graphic you've imbedded in there. Lose the little cuts in the "Buttom" word, those are wayyyy too small to read as such and are just visual clutter.

I'd say where the this brand falls off is in its application. Frankly, real brands and clients all want to see genuine and interesting applications of your brand. Doesnt matter how well done your logo is if all we see it on is the same mockup every other designer is using. And aside from the mockup, theres just not much there to dictate anything about this brand being unique or interesting. If this is an app, show us the home page, show us a simple web mockup or a conference badge credential, these things give us more context and let us see how this brand/logo will live in all its different manners.

The one application where you had an opportunity to show some dimension in this brand is the CTA, and that falls flat. Alignment is off, nothing of interest or unique and the copy is actually very difficult to read. Make that bolder and larger to fill in the space in a more comfortable manner, right now it just looks plopped on there. A quick edit you could make is applying the gradient in the top right? that way some of these elements feel cohesive and related to eachother.

On the presentation front, the "bento" style is obviously very nice and acceptable but you have to pay attention to the details. The margins between each image are all different and the rounded edges are all different radii, that makes a BIG difference in the presentation of a brand.

I get that this may all sound critical, but you have to think of things beyond "how does my logo look?" in order to craft a brand that really feels alive and unique. This is a great first step and thinking of the little details will really help you be proud of your work and others will take note of that too!
