yeah do it dude!!
No probs, it helps to actually draw your meshes too so you have an idea where to begin. As Vlad said earlier nothing is set in stone in terms of the 'right way' its a preferred way.
I would also recommend looking at the main muscle groups in the face and how edge loops resemble those, it makes more sense when you see it this way, you then understand how things work and the benefits of edge loops for animation purposes.
