Far be it from me to slam anyone for expressing an opinion, or even criticizing something they feel is flawed. However, your tone is both snotty and disrespectful. Considering that your own so-called "art" barely garners a comment from anyone, shooting your mouth off to an artist of Isikol's stature, whose works are admired and raved about by hundreds every time he posts, you come off more like a peevish child than even a creditable troll. While I'm sure it must be pitifully unpleasant to be you, you might want to consider working on your own self improvement rather than trying to feel important through impertinence towards your betters.
Took me a bit to make it out (her cape that is), so much red and orange in the scene that is very difficult to make out. This is only my opinion, my friend, so you don't need to listen to me if you don't want too... but want to share them with you...
I think having the cape on the pole would be clever and make the statement that you were looking to make if there wasn't so much orange and reds in the scene drowning it out. Since it is barely recognizable in the scene as it is, it might be better placed on Supergirl and tattered... which brings up my second point on this piece... Supergirl is too clean.
Here Kara has gone toe to toe with Doomsday, the killer of Superman. There is wreckage in the scene, her cape is flapping in the breeze, but she (and the rest of her costume) is spotless. I'd do some slash marks maybe on the abdomen area of her costume and some abrasions and soot smudges on her thighs. Think about how Dan Jurgens drew Kal-el during his fight with Doomsday for reference.
It is, as always from you, BEAUTIFUL work... but it isn't done yet, my friend!
