idk about this event but in the past winning entries in one event can't be used in another one.
I agree, but in my opinion my entry isn't the same as in the last screenshot contest.
There is a special set or map that you like? Well...use it! We would love to see how your imagination works, use existing S4 League official arts, screenshots, your own fan art or whatever you feel will look good on our forums! We have almost no limitations, in fact, there are only two - the image must be of size 1920x1080 and it must be related to S4 League. That's it!
I used an existing screenshot of mine, which won in the last screenshot contest, that's true. But I used that screenshot and spend time to edit it - creating something new. In my opinion, these aren't the same entries anymore.
Anyway, it's not in the rules or against the existing ones.
I think it's up to the S4 staff team to decide in the end.
