I like it, the storytelling is pretty clear to me. I'd say though to watch your contours a bit and sharpen them up. Right now your sort of on the fence between a softer style and a harder one. I'd go for a more edgy, tougher drawing.
where's pg 1-2?
cool drawings i like the wolverine panels on pg 3 the best
You did a good job on the Hulk. I like the expressions you gave him.
I think this the work is very solid. I particularily dig hulks expressions, particularily Page 3 panel 3, 4.4 and 5.2. Dave pointed out direction which is something you should watch. Sequential art needs to be viewed as a whole which flows.
There are some proportion issues with Hulk. His torso and legs don't quite match-up well in a few panels, such as page 3 panel 5 where he tosses wolverine. Hulks head in page 3 panel 1 seems far too long (from nose to neck not chin to scalp) and the angle of his jaw to the buldge at the back of his head doesn't align properly. It stands out way too much and detracts from the art. Panel 5 where he tosses wolverine into the car, has a similar problem. Colossus and Nightcrawler's heads also seem awkward.
These issues are rather nit-picky but I believe thats a testiment to the quality of the work. Keep it up.
You are headed in the right direction. There are a lot of things that you are doing pretty much right: like human figure and general story telling. I actually enjoyed reading these pages, and you have created a lot of interest - people want to see the other pages already
One of the things you really need to work on is lines of action: I see your overuse of speed lines as a way to make up for what you lack in clarity on action scenes. In general, the more speedlines you see yourself adding to a panel, the more likely you havent defined the action of the characters clearly enough.
Most of the best, fastests, more powerful action that I have ever seen in comics never needed any speedlines, it spoke by itself. If you pay attention to the style of the best artists out there, they barely ever need speedlines. When they do they tend to mask them by representing them with other, real world objects (like trails of smoke).
