Training myself

I started doing some 45min zbrush sculpts the other day and plan on doing one everyday unless I am crunching on some homework. I feel like 45min is a good amount of time to get something done but I make sure I don't go over my time limit. I'm hoping to train myself to focus more on the silhouette and overall shape of the model without wasting hours focusing on small useless details. Hopefully my speed sculpts will get better and better with time. So far I have done two of them and I wanted to post them up here so in the future I will have something I can look back at and see how far I've progressed. I won't be limiting myself to characters either; I'll be doing some environment sculpts in the future.
