They are all cool. I like the girl (looks like something out of a comic which is great!) and the pen sketches. Although one thing, the first pen guys chin is 90degrees, you should broaden it a bit so it doesnt come to such a point. So is the seconds dudes aswell, but I think it is more noticeable on the first.
Breath of life is also good, but I just dont like it as much because its just not my kinda drawing.
Now the photos:
That first pic is awesome, did you set the camera to take it, or did someone else take it?
2nd and 3rd are ok, but again, im just not a flower man.
