Ah sorry, my forum activity (and my mind) has been all over the place this summer, so I wouldn't be surprised if I neglected a few PMs. I'll have to go back and check for it.
It's not that I don't want anyone to use them--I'm actually very flattered that you pulled influence from me, but I just think that you can do better in terms of design. =P
My own characters all tend to have a similar, conservative look to them because of the style of their world, but for your world where your characters have distinct designs/styles, it seems odd to have two characters singled out in the same style. I can't really stop you from using the designs, but I do think that you have the ability pull out something a little more original for those two. Not calling my own character designs unoriginal, but they aren't the most diverse either. =P
