Hey guys, wasn't really sure where to put this so I thought it'd fit in here. As you can tell from the title this is my first attempt at making a signature so I'm looking for any constructive criticism you can give me. The main aspects I'm looking for help with are text and lighting, I just have no idea what to do when I come around to them.
Thank you in advance :)

(I put it there in case I change my signature later on.)
