To make that Reindeer:
Basically, just four different kinds of parts, you'll need to make two of the front and back legs
a body from that 1×6
Antlers, note the grain direction. Use a 3/8s round-over bit on both sides, the notch is cut to fit the notch in the body
rear leg, the notch at the back is about 3/8", round over on the outside only
front leg, again, just round over the outside edges.
