Liquid Metal Zac

I actually brought this up in another thread, but it was in the GD. Basically he would be grey with a silvery sheen, a single red eye, and MAYBE without the tendril. I like the tendril, but I feel like the skin would look better without it. His Q would transform his fists into metal blocks, his W would release metal spikes from his body, and I'm not sure what his E would do yet, but his ult would turn him into one of those crushing blocks you find in a plat former. The problem I'm having with his ult is how he bounces off the ground as a solid. I suppose he can push himself off the ground instead, but a solid would hurt more than a semi-liquid. His passive would have a melting animation instead of an explosion when picking up bloblets and when he dies. Last, but not least, he would have a bit of a metallic echo in his voice. Any thoughts? I think it's a pretty cool skin.
