Nice work
I like the Hitsugaya one (a bit of an odd resolution though), only issue I have with it is the Ice effect over the text makes it a little hard to read and becomes a little distracting.
The Renji one is pretty good too, but I don't really like the blue wash over him (the one on the left), if you had him as his normal colours, I think it would look a bit better, but that's just the way I see it. I still really like what you've done
