Just by going with what you provided, it's somewhat difficult to honestly know where you're at.
The proportions and anatomy could use some work. I would highly recommend to look at some Andrew Loomis or William Hogarth books - if you're interested in anatomy. Even if you aren't interested in it, it would still be good practice and help you fine tune some of your work. You'll also want to begin working on your line work some - try to do confident lines the first try. In addition, revisiting basic shapes and practicing them will greatly help.
On a side note, you can post your daily sketches here:
