Hi hesham
As you can see at present the challenge is currently held with one11.
However your post and image has been received ok, so it looks like you have solved the problems of posting. When the next Open House is declared or you get the correct answer to the ongoing challenge then hopefully you will have the opportunity to submit your challenge.
Incidentally your posting appears to be an Island Kittiwake. Please remember when posting you should try to make your challenge a silhouette, either created from a picture, or a 3 view, such as the current challenge from one11.
Hope thats clear.
