Hi Takowassa, thank you for your message. Sorry we would normally have contacted you before rejecting your work but there was a little hickup in the process.

The piece as you show here in the forum post is perfect!

The submission process is a bit confusing often, but you've submitted a small file (required) which was good, and a detail file which was scaled. The detail files must also not be prescaled, in this case no detail file was actually needed at all (only needed if you have a work that is larger than 100x100)
You can't 'remove' the current detail files, but you can replace them with the small images, so if you would be so kind to add the original small images as detail file for the 3 submissions you have and then resubmit them, we'll add them to the gallery as soon as possible.

Sorry again for the confusion, and do let me know if you have more questions!
