Okay so seeing as you got bashed p hard, I'll try to give a comment that isn't ignorant. To be quite honest, both of you are being just that. Let me tell you the essence of abstract art.
Abstract art is the art that uses color, shapes and composition in a way that it does not directly resemble anything. It can sometimes still slightly look like something (eg Picasso's work), or it can be intended to look like nothing (eg Malevich's black square). Because abstract art can't be referenced to the physical world, the only things that can distinguish good from bad abstract art is how well it was thought about. This sometimes requires an explanation, or even references of work made in the past to understand the artist's meaning with that painting/drawing/texture.
You quite obviously didn't take this into account when making this. I understand that you're not a professional artist, but the way you defended yourself is now invalid. One, because there is no reason for the composition as it is and two, because you appear to not have reasoned about abstract art enough to see that just telling others "you think it sucks because it's abstract" has literally no ground point.
So yeah. I could add more, but I think my explanation of what makes abstract art good abstract art would be enough for now. I might add that the one thing I did like is the yellow. It's a personal color because of your color blindness (given you weren't lying because internet and lack of background) and therefore adds at least some personality to your drawing. If you could make the rest up to par that'd be pretty great, but so far you quite clearly haven't.
