Warning: this post contains lots of cars, so if you're not into that, uh, hi

I make these with Sketchbook Pro 6 for iPad and I usually spend over 15 hours straight on these, so yah...
I've been doodling random things since I discovered pencil and paper...
I usually draw cars, I don't know, seems fun, right?
I'm currently 12, turning 13 in a month. yah 
A Koenigsegg Agera R on paper (still procrastinating drawing it on Sketchbook .-.):
McLaren P1 on digital (my first car I drew on Sketchbook that I found somewhat appealing):
Nissan GT-R on digital (my current personal fav, but happened to spend the least amount of time on it, only 8 hours straight):
Lamborghini Aventador side view on digital (eh spent quite a while on this one polishing out the polygons):
And here's a tiger .-. (most recent one, made with sketchbook pro 6 with a wacom bamboo tablet, spent couple of hours on it):
uh u can see all of this and more on my deviantart page http://samuelyap.deviantart.com
you can also download then for wallpapers (idk why you would download one of mine, but heh) there.
ya hopefully you find at least 1 of them appealing, still procrastinating drawings as I type this...

I seriously need to get a life...

Oh yeah one last thing, if people actually like this and want to request a drawing to be done for them, I'm really sorry but I'm not the type that keeps promises, so yeah :(
