That looks good, especially considering how you say you fail at it.
When I draw, I use a pen a lot, but how I do it may work with a pencil.
I just draw the outlines and things lightly, then I outline it. If I mess up outlining, then I go over it until I get it perfect. Coloring…eh, I don’t color much anymore. XD
Couple that strategy with straight lines (Or perfect curving lines) and its epic. Like this one, which a result of that combo.
