It was good.
Cracked up quite a few times. [such as Mirajane commenting on Gray's 'skivvies' and Natsu and Happy's reaction to Lucy's plan involving Everlue's toothbrush. XD]
Only thing is that I think they may have made Levy's voice just a bit too deep.
I agree with you about Levy's voice, however she does look older in the first few episodes, so hopefully one it gets to the Phantom Lord arc, her voice will change with her appearance(Not voice actress, just the tone).
