ok. i'll comment on both at once. in the case of the Demony vs. Tigerclaw pic, looks awesome. the claw scars on Demony look a bit too wide IMO, but then, i can't be the judge of something i haven't seen before. most of the stray cats i've seen have scars on the face, rarely anywhere else. the poses are great. capture the action well, but then, that part is, according to you, by another artist, so that part is irrelevent to your work here. the colours are great IMO. the background is considerably better than anything i could come up with, so i can't really say anything there.
as for Ira, she's improved since the last side-on pic i saw of her. chin's improved but still needs some minor adjustment. i like the work on the eyes. looks better than previous appearances IMO. but then, i'm a sucker for that specific shade of blue so that may be biasing my opinion a bit
all in all, cool. i liked the little Demony vs. Tigerclaw story too. sounded cool...
