I'm still a nub at Photoshop, and I haven't taken any courses on it until this semester. I'll post what i've worked on. Most of this was part of me learning how to use photoshop. I'd be glad to make signatures or banners for people for some extra practice also. Spoiler
Not asking you to do anything for me, but just a heads up from a photoshopper who made avatrs/signatures/banners/icons. I've done Photoshop for about 9 years, and I can say that people would probably want smaller sigs. Don't get me wrong, these are nice for a beginner (i couldn't do that stuff until my like, second year of photoshop), but the biggest "awesome" signature I've seen was probably 500x200. Other than that, keep up the good work.
Good to know :3 thank you for the information. Tips like that are greatly appreciated. Yeah i've only been working with it since ~October getting better each project. Some came out a bit sloppier than others haha.
