The layout looks great. Though I think you could do without the "spider-sense" close up on page 2, and move up the panel showing the random guy. It's kinda distracting right now, poping up like that in the middle of the action. That and maybe show a little more of the environment. I know it's just the layout sketch, but I can't really tell where they are. Is it a sports store?
The bit that doesn't ring true is the 2nd panel on page 3.
If you were right there with him in front of you - you'd be hard justified not to kill him - to my mind (my super villain is coming out) - its the classic James Bond death scene.
If however, he was unconscious and you were caught up on time and he was hard to get to, then I'd believe it (down a few levels in an awkward spot - something that you couldn't just pop across too.)
You have the space with the size of the panel to accomplish that.
Better, but I'm not feeling the drama of the last conversation. I'd try to give electro a gesture that suggests he's angry at the affront to his authority. Starscream it up! His current pose suggests they are totally relaxed and have plenty of time.
The pose looks strange on electro are you aspiring to be a comic book artist or is this just fan art
the action in page two is iffy. Spiderman is facing greenman and then gets shot in the back You are going to need to turn him around in one of those panels. I'm not sure what mr.brown jacket's presence serves on that page either.
page 2 panel 2, spidey with spidey sense, notices something behind.
page 2 panel 3, spidey turns behind and swings towards where he sensed another possible threat and sees a mysterious figure.
page 2 panel 4, With closer inspection, a close up of the mysterious guy is shown.
page 2 panel 5, spidey is so distracted that electro got a clear shot right behind and zapped him down.
There is some serious shrinkage/anatomical errors
on the arms of the characters in your latest update.
Overall you should be doing more gesture and
anatomy studies to help overcome problems
