New Blackfrost Skins look too skinny

Does anyone else think that the Renekton and Rek'Sai blackfrost skins look a bit skinny in some areas?

For example here are the turnarounds for the Rek'Sai skin: https://twitter.com/KateyAnthony/status/1230186274612334593 Her back legs look like thin black pegs, compared to her base skin (https://teemo.gg/model-viewer?skinid=reksai-0&model-type=champions) where they're fairly thick and covered by armor plating. I was wondering if Riot could beef them up while the skin is still on PBE? Maybe add a bit of ice to them as armor.

Now for the Renekton skin: https://twitter.com/KateyAnthony/status/1230186360918593536 The blade is REALLY thin compared to his base (https://teemo.gg/model-viewer?skinid=renekton-0&model-type=champions) or the recent Hextech skin (https://teemo.gg/model-viewer?skinid=renekton-17&model-type=champions). On those skins the blade is fairly thick, but on Blackfrost it looks like a thin blue line around the handle, maybe Riot could stretch it out a tiny bit outward while it's still on PBE?
