Tutorials, you need tutorials.

Minora - This is by far, one of my favorite signatures from you.
I did however think that it was a bit to large, and the C4D shouldn't have covered the focal.
The background was a bit odd, however it was perty.

Martin - While I did like it, it was a bit too bright, and should have involved more green in my opinion. The flow ended up going in two directions, however I liked it a lot.

Xoom - There was really no flow to the signature, due to the lightning coming from ichigo's hand, and the background tree thing or whatever was out of place.
However you did have some very nice color coordination, and even though it had its flaws, it looked very bad ass.
