Thats really good inferno! Top ones better .

I see youve improved, its a lil bland mostly becuase of the coloring its monotone mabey try brusing in some colors or jsut mess around with graidiants idk just my appinion.

yea I like the 1st one looks way better lol i dont like B&W tht much

Ok well the text placement is bad, it should be closer to the vocal point and a certain % over the render. There are tuts to show you how to do so.

The flow is good, but the background is too vivid and it takes a sec to actually see what's going on in the sig.

The aren't many effects around the vocal point to really attract the eye, you should try to use a light source, and read up some tuts on blending and bluring to blend the render into the background.

Good luck.

can you stop saying "good luck" it sounds like your sending him on some epic journey (your not right?) :p
