A dragon is your typical flying winged beast, with one set of wings and two sets of legs. A wyvern is a (usually skinnier) creature, with wings for front legs and normal back legs (think of a bird with bats wings and scales instead of feathers). Their bodies are as often as not snake like as well. Drakes are simply small dragons, only a few metres long. I think that's it anyway. Could be wrong...
I don't think this classifies as either, though. The closest thing it is to is a drake, but rather than a set of back legs and a set of wings, it's got a set of front legs and a set of wings. That doesn't matter though. Originality rules!
You really handled the angle well with this one. The head looks unflawable. The body is also good.
There's something funny about the legs, though. I think you've basically got everything there, except for the muscles that would usually connect to the back from the legs. Once again, get yourself a REAL pic of a rather muscle human being, and you'll see what I mean. In this pic, you should just see a bit of it underneath the animal's right arm pit.
The wings are also very effective. No real structure, but they still look good. Once again, I suggest you get your hands on some bats wings, on the internet or something, and see what they look like. I guess I'm lucky. I could go out at night with a torch and look at the flying foxes. If you ever get a chance to see some in a zoo (any bat will do, but preferrably flying foxes as they can have wingspans of over a meter, try and get the keeper to show you one up close and personal. Or get a pic off the internet.
Either way, good luck! The angle is superb.

"Thanks for clearing that up for me a bit. I think I do have a picture of a flying fox in one of my National Geographic magazines. I'll try that out the next time I draw a dragon. I'm currently working on a winged person drawing using a swan picture from National Geographic as a reference."
