I only see one design.

But it looks like a basic replication of a generic style.
Need's better lighting, render settings, and quality.

I hope you don't plan on putting these types of designs on a shirt.
I don't think it would print well. Or sell too well either.

I wouldn't start out designing that style.
There's not much to learn from it and you can't get too far with it.
It's very generic and unoriginal.

Definitely try other types of design as you get more into it.

Very well said.
For T-Shirts you dont want designs that look like a bunch of cluster cause the trend now days is like minimalist, hipster. Basically people want plain colors that go together with a simple design. If you ever need help picking out colors use the 'Basic Color Theory' [ Register or Signin to view external links. ] Anyways your designing is good but unoriginal like the guy above said. Im not going to lie for fashion, design it requires creativity (kinda ironic in today's society).
But please do not give up because of our criticism. We are here to help you improve and move on forward. Wish you the best.
