Both are awesomely creative.
However, as to the 2nd hole, I've never been fond of mounds so close to a green that you can carom an errant shot off them and onto the putting surface. With little or no penalty for a (slightly) crooked approach, such mounds seem like they're the inverse of a greenside bunker.
The solution, of course, is to grow the grass much higher on those mounds such that a favorable bounce is unlikely and a close recovery becomes problematic.
However, deep rough (like PENAL deep) is second on my list of pet peeves regarding "lazy" architecture. The primary offender, of course, is Stupid Trees.
In fact, I have just this moment "coined" a new phrase - "Stupid Rough".
Anyway, I'm not totally fond of the 2nd hole but think the 6th looks fantastic.
