I'm liking the text you're using in the images, but the spacing is making is a bit hard to read. This might just be me, but some spacing between the words under your moon image seems to blur all the words into one big word, it took me a bit to understand quite what it said.
Also the bio's words being cut off is disorienting too, I'd suggest maybe doing a justified orientation by adding extra spaces in between words using periods made of the same color as the background forum instead of cutting words apart.
Otherwise, I'm really liking the whole theme to the signature, I wouldn't advise changing that too much, just make it a bit more readable
