Ohh great, thanks Puffy - now I don't trust mushrooms on top of everything else!
Looks pretty cool, I think your mate needs to take his time though, tell him never to scribble with a tablet, he should make smooth precise movements - you'd be amazed at what's possible with just a little practice. For example, the shrooms face could be one smooth line that gets fatter at the base, little strokes for eyes, and another smooth arc for the head and it'd look much better. Also, tell him that if he makes a mistake, use the undo - never try and fix it when you can just keep doing it till it's right 'first time' - before long he'll be drawing all sorts.
