Wait, you did this in Paint? How?
The paint application in Windows?? Ms paint? Well, if that so, that must be difficult and time consuming to draw all of it. Although the OP could improve the drawing by using the line tool that curves 2 times. I could draw in MS paint by just using that tool, but it will really suck your time just to create a single character. 
Neverhless, I appreciate the effort the OP gave to his presentation, more importantly is the content even if the visualization isnt satisfactory.
