I want a really high quality camera, like ones on tumblr and with really high focus?

I don't know what camera would be best exactly, but I'm really in to photography and haven't got a clue. Preferably a Nikon or Canon or any camera better.
Pictures like this:

And although I said I'm really into photography, I really have no idea. My mom already has a Nikon, but I don't know the pictures I take never come out right and then the flash always eff's the picture up. & I kinda don't like Nikon as much as Canon, also she's very protective over it.

So yeah, probably too much detail, but thanks for the help in advance! C;

You are not radey for a DSLR yet, since you said you had no idea how camera works…
get a bridge camera and learn the basics first. Or you can also go get a Sony HX100v, t's not a DSLR, but it has 16MP, 30x and you have control over shutter speed, apertuer, and ISO, learn those first and then get a DSLR
