Red, for the love of all that's holy, how do I paint RED!?
But more generally, I'd like videos that focus on the core fundamentals. Everyone seems to skip them in their own tutorials, but some of us could use help with "how thick should the paint be" and "where do I paint highlights." The latter, especially: not everyone has good spatial awareness, especially when dealing with something at such a small scale and outside of normal experiences. I'd also like to see a wide variety of techniques. Too often only one way of doing things is shown, and that leads to frustration from those folks who don't want, or have trouble with, that technique. So, for example, if you do a video on using putty to fill bases, also show how to use spackle, or sand and superglue, or just sawing the base off and mounting on a clear hexbase. Cross-reference everything. If you mention drybrushing, put a link up to a video going over how to drybrush. If you do a new fundamentals video, go back through your old ones and update them with new links.
Frankly, there is no one good place right now to get all the info people need on painting miniatures. I hope Camo Specs can fill that void.
