Your voice acting needs a little work. The son's voice was fine but the father's sounded forced and took me out of it a little. The rest was quite good. I would say work a little on your art, but i think it was good enough.
I would be interested in seeing this continued in future episodes. Wasteland videos, such as this one are a bit overdone so you would have to rely on good characters and strong story arcs, which could be difficult. But if you could do that it has the potential to become a really cool series.
