I made a dragon sculpt and I am now trying to make a retopo of it, intended for animation down the line. However while I made a lot of sculpts and still models, I do not have a lot of experience with medium poly character models. I of course watched a lot of tutorials, but I have a lot of questions and desire for feedback…
Something that might be of interest to you Rurouni, a rock tutorial by PhilipK that was recently posted in the technical forums - http://philipk.net/tutorials/modular_rocks/modular_rocks.html
That Modular Mount & Blade tutorial is a gold mine, and it explains what modularity is all about really well. the 3dmotive tutorial is also recommended! :)
