Hey, it's not bad for your first try. A few suggestions,
-camera shake is ok to an extent, sometimes it's even considered a style. Look at some new tv shows, and apparently bad camera skills are in (out of focus, hand held shake, etc...) . But if you use all tripod shots, it sometimes looks equally as weird, depending on the subject. Mix it up.
- Always keep the camera between the light source and the subject being filmed (like in your room, the camera should be against the window facing you, and you should be facing the window, so the light hits your face).
-Check your audio levels. The songs you played were quite a bit louder than you speaking.
-Titles. There are so many options. You need to look at the "flow" of your project. I would suggest that the background be black (light blue isn't that gangster

and stay away from that typewriter style where it comes on the screen one letter at a time. Maybe try to find a font that represents your subject (like cursive for a wedding or handwritten or "Tag" for your video)
-Transitions. They can help two clips go together or a clip to a title. There should be a bunch of preset ones, but for now stick to "cross-dissolve" and "fade-in fade-out". I think a few of those in your video would make a difference.
I think it's a funny video. Don't get discouraged, just keep making videos, and know that whenever you post a video, people are always going to critique it. Just don't let it get you down. I liked it. Try remaking it and see what happens. Happy filming.
