Oops!
You don't have to re-submit a piece as a whole new art. Just hit 'edit it' up there, by the art and reupload new version/update ^
Why did you never correct and re-upload???
You certainly have improved in very little time.
This is 5 pixels too tall, you might need to sacrifice some clouds, please resubmit once you do.
Ahh, yeah I found that out after I re submitted it
