I've been watching this thread from a time but never saw the chance to give my humble input.
If someone ever, for whatever reason, tells you that drawing is about talent, then hit them hard in their face with your sketchbook and use that surface as a tabletop; it won't instantly improve your skills, but at least you'll have a portable training ground.
In all seriousness, this is a pretty nice and inspiring endeavor if you're passionate enough to go for it. There's a huge batch of Bay Watchers that have already shown themselves as accomplished artists, but we've seldomly seen their beginnings, those historical first strokes. I'm sure that nine out of them were born out of hard practice and an overall sense of challenging their own skills; the other one may just be a magical freak with 16 fingers and compound, bug-like eyes.
Maybe you would like to try bigger or more complex drawings, perhaps scenes with a few characters or objects interacting between themselves. I'd rather suggest to get out of your comfort zones, try drawing stuff you're not accustomed to, scribble down small narratives or comics.
Comics are great, drawing the same character again and again will allow you to gain more confidence and find your style, further down the road. Monsters are great to begin with, they're not judgemental with proportions and unusual features, while you get some ground to improve on relevant stuff like hands. Goddamned hands.
Keep on truckin'.
