Pretty Cool, Your definitely British lol, like House. (only im use to his acting voice)
And the guide good. If youd like to spend more effort though, might i suggest redoing it with a paper at your side that has the bullet points of what your going over? "Umm..." and such is very distracting and will take viewers from what your trying to show them. (im in public speaking class, thus my advice lol)
Overall great job though, i find it as a good guide to link for newby rooters.
Turtle bit me.I thought they were slow....they snap so fast. ................. <3
