Need RPD char design help

Ok, its like this. I have all the script I need for the moment on this project. Problem is, I am not good a drawing and animation. I am trying to draw a main char for my RPG. I have drawn an oversized pic of him for the inventory system. Easy enough since I took the time. But the full body chars I can’t seem to do. What I need is some tips and advice or possibly a link to a great site that would help. Anything will help. Thanks
