Hard to tell from the pictures - how is the counter top attached to the wall underneath it? I see that there is a bunch of rebar in the counter, is that fastened to any rebar in the wall, or is it just sitting on top of the wall?
If you have the counter rebar attached to whatever rebar is in the wall, or have some other solid attachment to the wall, I wouldn't worry about the strength all that much, as in order to collapse the counter, you'd have to topple the wall - which doesn't look likely. Your counter doesn't stick out from the wall that far, so there isn't a lot of leverage there that would move the wall...
Another option that might be worth thinking about is to put some sort of shelf brackets under the counter on the inside, essentially replacing those angle iron brackets you had holding up the forms with something fancier - I'd probably look for something in a black wrought or cast iron w/ scrollwork or other such decoration on it - make it look like it was a deliberate design...
