Like your other drawings, these are very good. I do not know where you live (except Australia) but I would recommend you join a life drawing session (I know that Melbourne has one but I don't know if that is anywhere near you). I attend one and use a masonite drawing board (it's lighter than a regular wooden one (I have 2 of those)). Also, recommend you get a small sketchbook then go out and about and sketch people. With practice, you will get better. With more practice, you may find out the direction you want to take.
