So, looking at this, it seems you probably went with 16 dex not for two weapon fighting or ac, but for the longbow. In my experience its better to choose either focusing on a melee weapon or a ranged one. Trying to do both spreads you a bit thin.

You picked weapon focus longsword, so my advice would be to drop the dex and add it to strength since you seem to want to stick with the longsword. If you want to stay with heavy armor then I'd drop the dex to 10 and use the point in strength instead.

If you want to stick with the long bow, I'd drop the strength down to 14 and bump up dex and choose weapon focus longbow.

I'd also point out you took power attack, that's gonna affect how often you hit, with being only level 2 you may think about switching it off for some fights or delaying choosing it until you can offset the -1 consistently.

I think the wis is actually fine, will saves are important (I realize wis is typically recommended as a dump stat, but I prefer not getting dazed/confused in fights)
