Your doing great, just remember to check the proportions of the limb's in relation to other parts of the body like the head or the core so you can get a rough idea of where they should end
For example:
The arms without the hand are about twice the head. From shoulder to elbow once the head and from elbow to the wrist is also once the head
The legs are usually the same length as the upper body from head to the ass
And from below the ass to the knee is once the core (from the shoulder to above the ass) and the same goes from the knee to the ankle.
I hope this helps.
