Suggestions on what PROJECT skins to buy?

So hello! Im looking for suggestions on which PROJECT skins to buy. Im on a budget, so Im only buying the ones I really like.

I will be buying the skins for their lowest price (So not First Strike)

1. I dont own Yasuo, but the 50% off is very attractive and I always wanted to play him, should I get Yasuo and buy this skin?
2. Im Buying PROJECT Zed. No Arguement.
3. Im considering PROJECT Fiora or Lucian. I have played them both, but dont own them, and I will only buy one of them If I do buy.
4. Yi and Leona are no-go's, I dont like Leona that much, and Yi's is cool, but way too expensive for me.

So out from that what would you guys suggest?
