Hmm, the background is really nice and it blends well with the render.
However there are some things that bother me.
Firstly: the text. The font and the placement does not fit with the rest of the sig. Whenever I want to place text along the lines of a render/effect (like his sword), I like to make the text subtle: A non-descript font and a weak color. And above all small
Secondly: The missing depth and movement. To add depth you should work more with shadows and overlays (that's how I do it anyway ) and for the movement you should add more effects like c4d's and maybe some interesting brushes. However, the render itself has no movement so this might be somewhat of a challenge. You should perhaps focus more on creating depth.
Thirdly: I think you should smudge parts of the render (specifically the bottom parts). It will help blend the render in even more and if done right it can create not only movement but depth aswell.
I'd give it about 6.5 / 10 as it is now. Keep it up, mate
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
