Hi, welcome to the forums!
Well, officially, you will be judged by your final entry, that's the most important part. The progress is there to see that your entry is genuine.
BUT as was the case last contest, interesting work in progress shots tends to be noticed - people can't help but look how the great piece was done. Also, it's hard to make an amazing piece without great progress / research in the first place.
(PS it would be best to ask questions relating the Worlds challenge on one of the Worlds topics just for future)
