Anyways it is safe if u submit it to the critiques and you'll have people to comment on your work whether it needs more modification or it's cool and ready to be submitted. Comments and critiques make u learn a lot.. and will make a design better. So no wasting time...

And don't forget to leave me a comment here, at the bottom space.. What u think about my design.
Thanks
