more color exercises!

so i'm gonna re-do that first sketchy thing (the picture i have on my last post) because it's not quite as effective as i was hoping....
anyways, here's some of my other ones i've been workin on!

i really like that second to last one.  that was one where i was supposed to key the color and i think it worked out really well. the last one though i don't think worked out so well...so i'll see what i can do to fix it.
