When looking at your Contro animation it is astonishing how far you came in just 2 years. Since you posted Contra Rampage I kept coming back to it since I simply love over the top violence and its absurdity.
While I never played either Contra or Double Dragon I still enjoy these parodies more than most of the rest on this website, partly because you guys put so much effort in it, it seems your portrait of the video game characters is believable. I mean they are literally beating the shit out of every single being(and even objects) that dares to be even close to them. So they gotta be lunatics.
Here are some parts that made this animation really worthwhile:
The animation itself. The outlines of the characters are always moving which brings so much live to even the calmer parts.
When the facial expressions turn from exagerrated to over the top freaked out. And you didn't overused so it doesn't become old and it's always nice to stress the dramatic effects of the situation.
The voice acting is nice and clean, setting up the frame for the action.
Also the end is really nice where the purple headed guy is so pumped by the game he thinks he too could take on that many enemies without any problems(and getting his ass handed to him).
There's only one thing I didn't care for: the dragon part. Setting up the expectation that they are gonna blow up the whole block as dragons and crushing it immediately can be nice. But it dragged on a bit too long, taking away the flow of the action. If it were shorter I believe it wouldn't feel so out of place, interrupting the action to a point where you almost forget the hilarious fight right before.
But that's just my thougts, it is nice to take a short break from the action to prevent it from getting too dull(1-2 heads exploding is fun, but constant explosions get boring pretty fast).
So long story short: Love your work and keep doing what you love, glad that all the work you put in it was worth it.
