The subtext don't work IMO. I think they should be smaller. Sig is not bad though. Nice flow. However, colours should be less solemn.
I like it just the way it is! Wonderful choice of text too btw. Really like the flow of it. I think maybe the top text should be a different font. But I see how you wanted it to be the same as the sub text. Yeah, Looks great. Nice job ^^
I'm not to crazy about the text you used for the word "knowledge" but other than that I really like it. The colours are well done and blend well with the render.
