This is an okay attempt. At least you did took the time to work on it though I'm not sure about the amount of effort put into it judging by the space it has. I can only assume that it would have to do with using the Fill tool for coloring and shading because I can see some "fill noise" (that's what they call it) on areas that weren't filled in, it kinda makes the picture a little incomplete though. I don't mean to sound a little picky on this but maybe you could just erase those see-through lines on the eyebrows of Yu-Gi-Oh and that little redhair guy. But overall, I think this is a good picture. It's a big canvas that nicely fits all four characters yet it just seems a little plain. You know you could still revise it if you're not all that satisfied or don't think it's that cute. I think the little pinkshirt girl and the little redhaired guy look cute btw. Good job on that one.
