Cool,
I like them, well I will be honest I don't like the last one, but not because it is bad, it just seems to disturb me a bit. Its funny how that works sometimes. Thanks for sharing.
The first 2 look amazing, I especially like the first one.
The other 2 are also impressive, they just kinda creep me out xD
Looking forward to seeing more of your things ^^
I actually like the last one the most. I think it's the most original one, and it looks like it has more meaning and emotion than the others, very good.
