A little too bright, and super harsh direct light.
If you want smoother light for free, don't point at the subject, but at the wall. You can also get away with keeping it on the camera that way too.
Another cheap and portable option is a small softbox style diffuser that will mount on a speedlight and still be small enough to mount on the body if you choose. They run about $15 on Amazon. at short range it does make some difference.
I have the YN560. Assuming you don't get a dud (which I did the first time, returned it no problem) it's quite the value. Obviously not as good as the Canon or Nikon equivalents but it's built well and does the job; I'd certainly recommend it. Also, this softbox is dirt cheap and works well.
I will say I have a couple of these, and they have come in handy more than once.
I have one of these. It works.
There's several ways you could go about it. Without investing in more equipment, you may be able to bounce it off a white ceiling.
Otherwise, you could buy a cheap softbox that goes over the speedlight to diffuse it, and then either hand hold it or set it down pointing at the subject.
Or, you can get a lightbox that you put your subject in, and shoot the flash through a side/top of the box. This method ensures that the background will be white, if that's what you're going for.
So for years now i've been using a couple Nikon speed light's with some small portable soft boxes (Kinda like these) even for my studio work (Shameless plug). My question is; i have no idea where to get started in "real" studio lighting, I don't know what studio flashes to buy or what triggers i need to go wireless with them.
If anyone has some input on where to start it would be great!
