Hiccup Introduces Toothless

I'm in love with this movie, HTTYD (How to Train Your Dragon).
Anyway, i BORROWED my brother's drawing tablet, because i like to draw and i wanted to experiment. Since i was already inspired in every creative way possible by HTTYD, i snagged a screenshot from online and set out recreate my favorites: Hiccup and Toothless.
i love them both sooo much.
So this drawing is really a practice for me, getting used to the tablet. It's my very first tablet creation, so any advice would be very much appreciated!
Don't ya just love this movie?
And yes, this is the scene where Astrid meets Toothless. The real pic of this is all over the internet, i'm sure you've seen it already.
i hope you like!!
