I think Pyke is nice designed champion and I am happy that Riot released another support for us supp mains to use.
But I have to say that the overall look if the base skin bugs me a little. The teaser looked awesome, but I know that a detailed mask like that isn't possible in-game. But the mask is even off considering the splash art. I would appreciate, if you could adjust the mask in the best way that is possible for you.
Another thing that bugs me, is that the dead person shows no sing of having been dead before. You know like, a little more grey and blue would make the model a lot more pleasant to look at. You know, as he has drowned or has been a corpse. I would be ok with the skin tone now, but if you could fix this, this base skin will be perfect
