Good start. Id suggest to work on proportions now for the most part. It seems you have nice clean lines, so getting your proportions down would be a great next step for you. Also, when sketching, draw lightly at first and then go over your final lines, this is especially targeted toward your Loomis studies, all of your lines are the same, when you draw the circle for the head, draw it lightly, it will be easier to erase or remove later. I dont know, maybe its just my computer, if so, then never mind. Hehe... Cant wait for more.
