Hi Scott,
It does not really look sick but it is on the small side and not symmetrical.
This link has an example of your current garlic.
http://dishbydish.net/2012/10/04/how-to-cook-garlic-without-smelling-like-garlic/This link has a larger, more symmetrical garlic (not perfect but better)

Yes I want robust over tall and skinny. It is actually the relative size of the bulb compared to the stem. A smaller garlic tapers more gradually from the stem into the bulb, while a large garlic bulb will head out at basically 90 degrees from the stem.
Thank you for your interest, Scott. Hope this helps. Please ask for more clarification if needed.
