Hey! Well, I don’t really have much to say in this case. Technically, it’s very well executed. You have a really strong technique with fineliners! (I wish my traditional drawings looked like this haha) However, I can’t really give much feedback regarding the design. I’d recommend that when you ask for feedback, you try not to leave it too open-ended. It’s better to provide some context so people can better understand what the drawing is about, or at least specify what you’re struggling with during the process. That way, it becomes much easier to give helpful feedback :D Anyway. What comes to mind is that, for the spheres, you could add some shading (depending on the light direction) to give the eye a bit of visual rest, since everything currently has texture. Not everything in a drawing needs to be 100% defined. Letting the viewer’s eye interpret certain areas can actually make the piece more interesting. Once again, great drawing and technique! :D Keep it up!
