I thought turning some of the things I do in RL with my siblings into a thread would be a good idea.

My brother would draw something and show it to me for a critique, and I'd re-draw it showing him, "How I would do it" and visa versa.

So that's the gist of it, you post a drawing that you really need help with and the other person shows you how they'd go about doing it.
Nothing fancy or time consuming, just a sketch of it would suffice.

If anyone wants to give this a try, then I'd be willing to help the first person out.
