This is an exciting time, I'm in the process of beginning a new model. My modeling skills are not the greatest, and I often find myself in frustration as my mesh ceases to flow correctly. If anyone else ever experiences similar dilemmas, try this, it helps. I drew a few quick sketches of what I thought I wanted, took what I liked from each of them, and ended up with a drawing shown in the first upper left image. I then drew out better rotoscopes, clarifying just what I wanted, and making sure I had a clear idea of where I was going in specific areas. I then suppressed the extremely strong urge to jump on the computer and start modelling. I dug through some things and found some cheap modelling clay. After a few hours, I had a decent representation of my rotoscopes. If you find yourself struggling with getting the basic shapes down, and the flow of the model, forget about the computer until you get the basics of real life modelling--at least, that's how it is in my case ;) Then, you can either scratch your patch lines into the model, or bake it and draw them. I took a toothpick and put down my basic layout, and it helps so much. I was able to determine my 5 points, and work the layout of splines with more ease than the computer allows. I am only posting pictures of the head, the body is still a major WIP. This technique is nothing new, many people have done it before, but if you have not and are struggling with modelling, I HIGHLY recommend it.
Only one side of my model needed the layout drawn, so I got somewhat creative with the other side (as you can see in the final picture). (boy did that take forever...) (sorry for the poor quality pictures) (I'll stop putting things in parenthesis now)
