Well, they look like great beers but definitely not "roasty"! If you want a roasted flavor, you have to use roasted barley or at least more black patent type malts. Chocolate malt does have a certain roastiness to it, but nothing like roasted barley.
We have a pretty good database, and if you check out the stout area: Stout
you can see recipes for classic stouts. Your recipes above aren't bad at all- but if you want a roasty stout those recipes won't give you that.
