Kicking off bad habit

my bad habit is , when i start to draw then i feel bored by it i stopped..leave the artwork unfinished (usually artwork that has complicated background in it) . I love painting Environment stuff because i like to evoke the moment of certain era/times/mood, but it also need a lot of work too ( research is super important, as well as texture)... im still had a boat load of stuff to learn environmental painting... but desert is easy
