I came in here to give you some feedback for your latest sig but I had noticed that you asked for some feedback on this one a couple of weeks ago and I thought that whilst I was here, I might as well give you some feedback for this one too.
As it goes, I really like the way this one turned out. The background is really nice. One question I have though is whether that is a created background or is it a self-created one? If it is the latter, then I am very impressed with it. The lowered-opacity Gabriel fits well into the background but could have been lowered a bit more, for my tastes. That being said, this is a great signature. The colour scheme is great and both of the renders are great. I like the feather on the one on the left.
Excellent work...
This one is a sig that I really like, in terms of style. Of course, I was the one who wrote the tutorial on how to create some aspects of it, so that is not completely surprising. To be honest, this sig is great. As you may or may not have noticed, I like more compact signtaures. I look at the Gabriel one and this one and I just like the flow of this one much more. With less space to cover, you are not trying to just fill space, like I find myself doing from time to time.
As for the content, it is really good. I made one that was quite similar to this but it never saved properly and I was a bit gutted really. That being said, I think you have done a Death Note signature better than I did and that is commendable. The only negative, for me, is little details. For instance, I don't think the render on the right looks like it fits in because of the colour. Also, I like to add a drop shadow when I use layer masks as it helps to add some definition to what you are doing.
That being said, I am glad I could help you make this and it is a great job.
