The end result looks great! but I watched over your intro out of curiosity and I have no audio right now, but you don't cover the process of creating that base mesh do you?
Do you just show how to go from the base mesh you have to that final render?
If so, you might want to create another set of tutorials on creating the base mesh for others to learn much more! You seem to have good skill here though and just thought that I would give my feedback based off of your intro video, however I could be wrong as you may show how to create that I just couldn't listen to the sound as well =\
I myself know how to model and such, I was just thinking to ask, for other people that may be viewing and interested in the post, not that many people have viewed it though to be honest, which is surprising because the renders look great! Perhaps the title didn't catch their eyes?
