I think your voicework still needs a good deal of practice. Right now your clips don't sound like you are playing a character, they sound like someone reading the lines from a script. This doesn't have anything to do with the lines or your recording devices. What is missing here is the acting. There is no change in your voice, patterns of speech or intonation. This is especially true in your female voice (?) which sounds exactly like your regular, very much male voice. It doesn't sound anything like Liz Shaw, I'm afraid. If voice acting is a passion for you, I suggest you keep on practicing it. Start out with trying to nail a single type of voice. Look into tutorials about imitation, read books about voice acting, and most importantly - go for drama lessons! Pretty much every city in the world has one or more hobbyist theatres that welcome new members, and those are great places to learn about acting.
