I like you.
You are one of the few people I know who likes to chalenge themselfs with NSMB sprites. I think that your submissions were great for the fourms.
Anyways, what game did you get that yoshi from? It was a great match with the other sprites. I liked how you were being creative with the fireballs and yoshi's toung. I think that you should make some more on your free time. The more you do, the better you will get, and you might be one of the first people on newgrounds to make a NSMB flash movie movie with a good, long story line.
