I think this is alright, average like BCB said. Could definitely use some work. I think first you should put a border because the edges look straight up weird. The sig as a whole is way too bright, and the coloring of the text is poor. It's just kind of plain.
^^ agreed. Text doesn't fit at all but thats alright text is hard to nail and everyone had/has problems with it. Its a good start. I think the colors and brightness is the problem here.
