What they are trying to say is that it's terrible and you should do better.
There you go, immortalshippo's mom. I can see that your son likes to draw, and if you loved him you'd buy a real art program for him so that he doesn't have to make shitty, pixelated bitmaps. Shippo's (Hippo's?) artistic talent is being stunted, and if you're not part of the solution, you're part of the problem.
And don't let your son hang out on such filthy websites, either. This one will courrupt your child and some day we'll convince him to shoot up his school. You'll be one of those mothers on Fox News who's all like "He was such a quiet kid, just stayed on his computer and drew on shitty ol' MS Paint. I never suspected he had it in him." You never suspected it because you're a terrible mother who neglects her son.
Or maybe you don't neglect him enough. Let him delete a freaking picture.
So... back to talking about you, immortalshippo. Practice drawing. I'd like to say you've got potential, but since have no idea what I'm talking about in this artistic department, I'll say that I think you have potential. For what my thoughts are worth.
