Hello there!
I understand you have a few questions regarding the Gear Design Contest (Tank Edition). While we have no plans to create an official discussion thread at this time, you are more than welcome to ask any questions you may have here!
Here are a couple questions we've received that have been addressed so far:
Q: Would you like us to present both the front and back of the armor, similar to the designs shown in this previous dev blog?
A: Yes, we would appreciate if you can submit entries which we can confirm the front/back like this one!
Q: While I'm sure the gear will be unisex, can we add notes for any variations in the design for males and females?
A: You certainly may add notes! If you would like to have some small changes to the design depending on gender/race, you're more than welcome to add those notes in the entry.
The dev. team is looking at your ideas, so don't limit yourself with worry over the illustration quality. If you have an awesome idea, be sure to submit it!
