Very nice! I like her somber/intent expression in this piece - she's beautiful of course, but you get the sense that there's a lot more to her than looks.
Minor crits - the sword placement is awkward. If I were standing with legs just starting to cross and holding a long heavy object in only one hand, the blade would most likely end up pointing in the same direction as the forearm, rather than angled inwards (which puts all the weight on the wrist, uncomfortable at best).
And, um, keep in mind that a bald eagle is about four times the size you've shown here? The one you've drawn would be small for a redtail hawk much less our nat'l symbol.
