I love how your line work is quickly evolving!
One thing I wanted to add is that you may want to consider strengthening your focal point when it comes to lighting and hard edges. Much of your rendered work feels pretty soft (especially seen in the environments) and I think that putting further emphasis on your lighting would really help bring much of the stronger elements out. Keep pushing, you have something great in the works.
hey! you've got one unique style! i had the same idea with weekly plan -but somehow it got lost - then i did what i thought i should do/the first that came into my mind. i would love to see it, when you've worked it out!

Hey dude, getting better there. I like the painterly approach you've been developing, those quickies are really nice.
Still I suggest a lot of reference studies, really simple, in pencil, to make your proportions and foreshortening better at places. keep it up.
