Drawing is alright, but completely would not work as a t-shirt design. I don't know if you're planning on having these made, or use them for a contest or something, but you'll have to reduce the amount of colors you're using. I count 15+ colors. Assuming you find a place that will print a shirt with that many colors, it would be pretty costly for a shirt. If you want to get into t-shirt design, practice limiting your palette to 3-4 colors maximum, including the color of the shirt.
Thank you man this is only the model, the background isn't going to be there but the amount of colors will be only 4 but thanks by the way.
