How about finishing it? 

That is exactly what I am going to do - it is going to look much better! ^^
Besides this, I am working on something on double size paper (painting size), non-Simpsons, something from my novel 'Belial', took me 10 hours and I am only done with the outlines. If anyone is interisted...

My personal to draw list:
- Lisa Simpson - You´re my satellite
- Sarah from my novel 'Belial'
- Comission, G.H.´s women
- Lisa Simpson & Milhouse - Summer wine
Lrrrve

Learn the construction method. Read the "Cartooning with the Simpsons" book. Try some grabpiccing first... good luck!
