milk, i've just watched the first 3 videos. and although i agree that you do talk quite slowly, i found them easy to follow.
my only real criticism is when you switched to the game mode (or whatever it's called?) the scale of the objects on screen was tiny, similar to when you were working in photoshop. so although i could follow what you were doing by your commentary, i couldn't easily see, plus there was a lot of wasted screen space in the tutorials as a result of the focal area being so small. not so bad when you were in unity's edit mode.
i hope my feedback isn't discouraging at all? i have just subscribed to your youtube channel, so i definitely think they are worth watching, and i look forward to seeing the workflow from blender to unity.
