Hi,
Sure I can change the color of the tracks and the wheels - no problem at all. And I'll match the color inside the caboose to the sky. and move the bubbles.
Concerning the production of your cloth label, I checked a few sites on the internet to see what is possible. If your label is a printed clothing label, then you can have the gradients (different shades in the background), but if your label will be woven, then you cannot have the different shades. Here's a link I found explaining the differences:

Thanks!
