While I do sense a lack in quality compared to the first four comics presented at the contest, I can still see some potentional. It just seems that now that the comic has become a "job" the creators seems to have lost a bit of the spark they had.
The jokes are flat and they run medicore throughout the entire strip - this is the case in all of them - and they don't really bring out a laugh. Of course, this is entirely subjective to persons humour. I think I can say that compared to, let's say, Stolen Pixel, a comic that also have a set of jokes running through the entire strip, Critical Miss doesn't seem to manage to achieve the same sense of acomplishment.
But then again this is just my opinion on a subject were everyone can, and will, have their say on.
This just ain't my cup of tea, but nonetheless, good luck with it in the future.
