A good sentiment although the image is a bit flat. I assume this is a T shirt? perhaps a model wearing it would have better effect, maybe in a loving pose with someone of different colour for added impact?
I had to think about this one a few moments to realize what the message was. The actual image is good, but I think it need a little adjustment to bring out the nice colors and texture.
The sentiment works but the image itself is not doing a lot for me. Mostly making me feel like the tshirt needs to go back in the dryer for a few minutes to get the wrinkles out, which is probably not what you want me to be noticing.
I certainly agree that love knows no colors. The shirt is faded and the colors are washed out. Are you trying to say that this was an old problem that has been solved in the 21st century?
A shot of a t-shirt would be much more interesting if it were on a model (who was perhaps demonstrating the motto?), but even as is, it's dark and needs more contrast.
