Hey there!

So, i guess i just started drawing ~for real~. I've drawn in the past, trying to copy photos, getting frustrated and then leaving them unfinished. I always start things but never finish them, actually. I'd like to try this seriously this time.
I've started reading Drawing with the right side of the brain. This is the first exercise, drawing a person from memory. I just have put detail on the head as i didn't want to make a mess trying to colour the clothes. I spent less than an hour; i haven't made a big effort as i didn't feel like it today. So yeah, here it is. I know it's really bad but i'm quite happy with it.
Some feedback would be appreciated, but please note that i'm a total beginner. Also it would be great to hear your thoughts about where i should go next when i'm done with this book.
