Not bad man, keep making improvements until it's as nice as glass without the breakability . Try using your ingeneuity to make homemade percs, diffusers, ashcatchers, whatever you can think of man. That's the fun in making your own pipes.
Those cups are perfect for a mini-tube. I have one that i cut, then added a pill bottle perc. I'd suggest a different downstem, maybe a metal or wooden pen, or some small metal tubing. Great first homemade. EDIT: About the big socket, search around the house for some sink screens.
