Checking out the thread you've made, you have the edge to compete with those professional thread designers themselves at the services section.
And I like the color combination of that example thread you've given. Are you depending to the color that was demanded by the company or you are the one that's deciding for them?
Trying to help you out with the size of image per thread but I haven't seen on the meta section that there's a thread for that or I didn't just dig the latter part.
