I believe this was the first time for both of us working with 99designs. Estrella worked well with me to meet specifications for all my book covers (two pdf print covers and jpeg eBook cover), illustrating and designing with stock imagery to make great marketing visuals for my story.
There was some frustration over copyrighted images, although my frustration wasn't directed at Estrella. My designer worked with me through the issues.
I will likely contact Estrella de la tarde for future book cover design needs.
