From a design standpoint, I'm not feeling it at all. Its just way too simple, like you used the basic patterns in photoshop or just any random pattern to design it. I have the 3d one in mind and it just looks terrible. Putting a bunch of stars on a hoodie really isn't that hard.
But then again I don't know how it will turn out. Hopefully these are VERY ROUGH SKETCHES. Maybe the final product will be better. Anyways, I'm not hating, just giving some feedback. And I hope you do get your designs going.
