Honest Opinion on the first one? I hope your feelings aren't hurt too easily :shock:
It looks bad, but here's how to improve it.
Always add shadows, it brings more realism to a fake than any thing else.
Don't enlarge the sprites. Not unless you plan on going inside and fine tuning the parts that start to look pixelated and blurry due to the magnification.
Kintaro's head looks like it was fudged when the sprite was cut out as well. I'm not sure if that was your doing or just the sprite that you used.
If you are going to add text, use a more fitting style. I believe
www.mkwarehouse.com has downloadable fonts for PC systems from all of the MKs. On the same note, with the addition of "FIGHT" in the screen, you should make it the proper size or not include it at all. Currently it looks like a screen shot taken at an inoppotune moment, as if the word is just coming on or near gone.
The pillars are so cut and paste it screams at the viewer. Either extend them all the way down so they look like foreground objects, or work them into the scenery, so they look like 3D objects from top to bottom.
The Water/Sky look good though
On to the comic...
Try putting all the images on one sheet, just like a comic book so you don't have to click a link for every panel.
If you want Sub-Zero to speak first, place his text higher up in the image as well. Since most folks read from top to bottom and left to right, Reptile seems to be answering Sub before he even asks speaks. So the flow of the whole thing is off from the start.
And frankly, it wasn't funny...but I'm not sure if it was intended to be funny in the first place.
Keep working at it!
