@jesperfriis hey man, it is a cool stuff, I really like it.
Btw, since you have done your final, btw there are a little bit problem in your thread, such as your final size dimension and concept sheet dimension. As far as I have known, the concept sheet must exactly 2048*2048px, and your final concept/ illustration must more than 2048px, in height or width. Please recheck the rule once more.
I wish you read this before the time end. Thank you.
