Congrats on getting a tablet ! Digital art will become atleast 200% more fun to do from now on.
That looks great for a first tablet picture. I remember when I first tried out my tablet, I was no better with it than a mouse, haha. It took me quite a while to get used to looking at the screen while drawing on the tablet. After getting used to that, it becomes almost as natural as drawing on paper. Almost, but not quite . But it is tons more versatile and convenient than paper.
