What does a dry orchid look like?

[annaverity]

Hello again! I'm a newcomer to this orchid thing (see this post), and as such, I've got yet another question about caring for my plant:

What does a thirsty orchid look like?



These pictures are of my plant (a Dendrobium phalaenopsis), and I'm worried that (1) the base of the stems are drying out; and (2) the leaf that's cracking is dead.

I just ran water through the pot, and it's draining now, but other than that, is there anything else that I can do to bring my plant back to full health? Thank you all in advance for your help!
