Can you do a better job with his image on a hirt?

Greetings,

I recently, had an image done on a set of shirts using DTG. I'm somewhat pleased with the outcome however the more I look at the shirts, they tend to be, not as vivid as the original design I created. I'm new to this DTG process so I attached a link to show what I'm really speaking of. In the image, you'll see my design image (left) and on the right, a photo of one of the shirts produced. I wanted to know, will this be the best output I can expect based on my image that I created?
