Thanks to everyone who liked my post and are praising in the comments. But let me say 2 things.
Why I said I don't really know how to use Photoshop: I did it in the third try (it was 1 try per day) and I just realized the healing tool in my second try. And the stamp tool? Jezz, it took me too long as well to realize how to use (I know, I'm dumb cause it's not hard, but somehow I just couldn't use it) and the eye... I'm sure there's another way to do it in more time with a higher quality, but I tried to so it "by my own method" and OH MY GOD WHY IS IT SO HARD
But anyway, thanks everyone, I really appreciate S2
