All I can say is... Im not too fond of the java tool. It defeats the purpose of RMD, and that is to show pictures being drawn.
And Im not too fond of drawing pictures from a reference picture either, because it wont show your personal drawing style and who you are, copying someone else shows you're just good at copying... (and then you'll say that there are drawings from reference pictures and java tools among my favourites but hopefully they're of the minority).
Other then that... Im slowly improving my own drawing style (I... hope...). Just you wait. One day Ill rise high and mighty and be super powerful and you will all bow down to my awsomeness of eternal doom and think just like me because you want to be just as awsome...
