Recipe looks pretty good. In line with the others, i'd drop the biscuit, throw in some amber, and slightly increase the choc malt. Personally i'd stay away from the roast barley as i find it creates too much of a burnt taste for a porter. I like my porters choc tasting though. I also prefer an irish yeast as has a lower attentuation and the residual sweetness sits nicely with the choc malt.
My favourite porter consists of base malt, 400g of choc, and some crystal malt (i think 150g or so) , simple but elegant.
I also think your bitterness is a bit high, i'm calculating 41 IBU's which i think is about 10 too high.
