If you're brewing an altbier, keep in mind they're kind of tricky. They require ferm temps on the colder end of the ale scale (say 60˚F), and usually a lagering period (a couple weeks cold) to really make em nice. Since you say you've never had one, here's a couple notes on what you *hopefully* are making:
Overall Impression: A well balanced, bitter yet malty, clean, smooth, well-attenuated copper-colored German ale.
Color: Orange-bronze to deep copper color, yet stopping short of brown. Brilliant clarity (may be filtered). Thick, creamy, long-lasting off-white head.
Aroma: Clean yet robust and complex aroma of rich malt, noble hops and restrained fruity esters. The malt character reflects German base malt varieties. The hop aroma may vary from moderate to very low, and can have a peppery, floral or perfumy character associated with noble hops. No diacetyl.
Flavor: Assertive hop bitterness well balanced by a sturdy yet clean and crisp malt character. The malt presence is moderated by high attenuation, but considerable rich and complex malt flavors remain. Some fruity esters may survive the lagering period. A long-lasting, dry, bittersweet or nutty finish reflects both the hop bitterness and malt complexity. Noble hop flavor can be moderate to low. No roasted malt flavors or harshness. No diacetyl. Some yeast strains may impart a slight sulfury character. A light minerally character is also sometimes present in the finish, but is not required.

So I tweaked it a bit to hit style guidlines for ya. Having just brewed a minimash altbier 2 weeks ago, I have some sort of idea how even a tiny bit of dark grains will throw off the color. From 4oz chocolate I ended up with "SHouldn't-a-been-a-porter alt"
Anyway, here's my results after tweaking the chocolate malt, and adding your hop suggestions...

By stylistic guidelines, it's also spot-on for a 7A - Northern German Alt, too.
hope that helps.
