First of all study anatomy especialy if you'd like to draw supes people and don't be afraid to use references for rawing stuff.
From a storytelling point of view is not bad at all.
Page 1 : according to me the page layout is good, but in my opinion it was better to make the first panel more relevant (bigger) and make the rest smaller, especially the panel where we see the finger pressing the botton an inset panel can be enough for it.
Page 2: I like the layout of this one, maybe was better if you drew the girl looking above in the 3rd panel and a cast shadow on her face (of Supes off panel) could improve the effect.
Page 3: Like the first 3 panel sequence, but please show some danger in panel 1 (smoke, blasting, etc..).
I don't like the last 3 panels sequence tho. all the panel suffer a bad layout and sizing. The winning Supes panel is too small and the Luthor fist pane is too big
Hope it helps
Yeah thanks for the feedback. Every little bit helps.
At a glance I'd agree to take more time studying anatomy: look at how other artists do it as well as learning the basic rules about muscle composition, proportions and facial expressions.
Your perspective on page two, panel four is so extreme that it'd be difficult for even the most experienced comic artist to draw it convincingly - Superman looks flat and his right foot is being forced into a very difficult shape to draw. Also, on the last panel of page two: remember that your perspective is looking down towards the ground, this is going to add another pane of perspective that is absent here.
Finally I'd advise using a bit more shadow to suggest shape on backgrounds, objects and people. This will also add a nice amount of contrast on your pages and keep it interesting.
Those a re you some words of advice: on the plus side, the story telling is is strong - it flows nicely between panels - and Superman's costume is looking awesome! Is that the way he's dressed in the new 52 or did you design that yourself?
Thanks for the feedback. It is the new 52 suit, I regret choosing it because it's hard got too many parts to it compared to the original.
