There are a few other options to consider here as well.
While the Cooper tutorials are (to me) the defacto standard for creating a human character these days you may want to consider some alternatives.
Modifications/AdaptionsCan you modify an existing model to meet your needs?
While it is best to have a solid working knowledge and the experience to go with it these assets don't appear overnight after a good sleep. As has been mentioned it takes time, patience and perserverance.
Rather than get stuck it might prove beneficial to study, modify or even cannabilize existing models.
Purists that will only use models they have wholey created have already mastered the art of patience because that route is going to take a long time.
Paid TutorialsPurchasing tutorials that go beyond 'free stuff' must be considered.
It takes time to create good tutorials (thanks Colin for taking that time!).
Where static webpage or print examples don't provide enough video tutorials may provide what is missing.
Paid tutorials help support those who take the time to put these demonstrations together.
(Note aside: Colin if you ever create a video version of your Cooper Tutorials I'll buy it!)
WIP and Teaching OpportunitiesAnother alternative is to begin a WIP here in the forum and post your step by step progress toward the goal.
This provides an opportunity for others to give feedback and help you (the artist) to articulate and extend your knowledge outward instead of only internally. In other words, teaching is learning! When you demonstrate how things are (or are not working) you cannot help but learn.
Success?The secret to success (that really isn't a secret) is getting involved with others in your common areas of interest. Anyone who has experienced success should be able to look back and see who helped them along the way. Thanks to Colin Freeman we have a great tutorial to guide us through the rough spots. Thanks Colin!
A few other words to throw into the mix:
Assess and acknowledge what you already know and have learned. (Access this information!)
Don't fear rejection. (Where one door closes several more usually open)
Understand failure is just a temporary condition. (Caution: Only allow acceptable risk)
Learn from mistakes. (Make lots of them but see above)
Get involved with others of like interest. (Make friends. Have fun.)
Teaching others is its own reward. (Best reward going)
Give credit where credit is due (Support those that support you. Whether paid or otherwise credit those that provide inspiration, information and support that you find useful.)
...and try to stay on topic!
