Love the first one, nice clean and a good use of color groups. +
Second one I'm not feeling that much. -
I assume you were going for a different color of wolf, I'd suggest you use Illustrator and use lighter colors for the brown, the point will still come across for a different type of wolf, and the green could be a little bit desaturated/lighter [only a tad]
Loving the effects and the background. To start with, the Multi[HAX] is what I'm not really feeling, just the hax bit. I feel it's a little too dark and fades into the background a little bit. Needs to pop out more so maybe brighten the color or increase the saturation. If anything put a soft white glow around in a little. Anything to bring it out a bit more. -
Features are perfect and the list of the capabilities pops out well and stands strongly amidst the banner. The yellow title works well somehow, though fades a tiny bit too strongly at the bottom. +
Finally, the Credits section. I'm not loving the multiple colors and believe you could make the credits a mid-white or something of the sort. Try and reflect it to that of features list. It simply doesn't fit in well and the mix of colors sort of simply collage into the background, a little bit of eye strain. -
Could simply do the credit sub-title, as in 'creator' and 'offset updater' etc as a white, just like the features list, and then the names/the credited in a blue or yellow, something that fits with the color group you've been using for the entire thing.
Hope this helps, any questions feel free to ask me here, pm, vm or skype.
