Jake, I think you're off to a great start here. If I may offer some criticisms...
The first thing I would say is the choice of font. I'm not as much of a stickler as most in the hand written vs. computer font (I actually prefer computer fonts depending on the handwriting), but the font you've chosen is not quite right (It looks like comic sans, but I could be wrong). Check out
http://www.blambot.com to start. They have great fonts, quite a lot of them are free to use.
In terms of the art, I think you've got a great base. Character designs are solid, you've utilized some good perspective, angles etc. The one thing I would say you might want to try is some variation. By that I mean varying line weight, color, perspective. The entire story almost seems to take place in the same season, in the same small stretch of land...try playing with different times of day, seasons etc. ... different seasons would even play up the plight a bit as it then takes place over a longer period of time.
The only other thing I might mention is the concept itself. I'm not completely sold on the idea of a 'trolloholic'. When I think of 'oholics' I think of serious addiction. Given the lighthearted way you've addressed this, perhaps a more classic theme might fit better. Maybe "Don't look a gift horse in the mouth"?
Sorry for the long-winded reply... just my two cents.
