Solstice, can you tell everybody what your goal is, what target as in quality you have in mind if any? If your just having some sketch fun thats fine also. I think some feel your not listening to advice given, but im not totaly sure you actualy wanted any to stat with, either way keep going and have fun.
If you do want to move forward, start making just heads as your main project, and make these sketches in between to keep it fun. Spend a good 4 hours on one head, not only will this improove your work, but it will keep you inspired.
