Critique my porter recipe (please)

I put together a porter recipe with advice from others on this site, and info from the Anchor site, for a version of a porter similar to theirs. I Plugged it into brew pal for some help, but I'd love some more experienced brewers to weigh in. It doesn't have to be spot on, just a in the neighborhood (and drinkable) Here we go:

7 lb marris otter
2 lb 2 row
1 lb crystal 70
8 oz chocolate malt
8 oz dark Munich
2 oz black patent

1 oz of northern brewer at 60min

Wyeast northwest ale

5.4% abv
29 IBU ( maybe a bit low?)

My suggestions are as follows:

Add a little more dark roasted malt content, you are at ~6% which I don't think will make this as dark as it should be. Lose the 8 oz of dark Munich, it's not really enough to accomplish much IMO. Consider adding a small quantity of darker crystal for more complexity instead. 29 IBU seems OK but if you want more and/or a touch of hop flavor use a small (1/2 oz) addition @ 20 minutes.

9 lb pale malt
.75 lb crystal 55-60L
.25 lb CaraAroma, Special B or other 120-150L crystal
.75 lb chocolate malt
.50 lb Carafa II (much less harsh than black patent)

1 oz No. Brewer @ 60 min
1/2 oz No. Brewer @ 20 min

+1 to a 20 or 30 minute hop addition

Why 7# of MO and 2# 2Row?

Here is my Porter (Fuggles would probably be a better hop choice):
