He's probably not the sort of player you might assume he is!
I think a lot of people just assumed his main asset would be speed, when in fact it's not.
He's got great acceleration, but his top end speed isn't spectacular... don't get me wrong - he's fast - but probably not got enough out and out pace to be an international winger...
His feet and agility are great though. He definitely looks very comfortable technically at the ruck and is good at judging when he needs to go in, unlike a lot of league converts.
What he is, is probably one of the best footballers in the UK. His passing is quality.
Although he hasn't used it all that much, he looks to have a good set of kicks too, a couple of grubbers have shown this.
He can place kick aswell, although, again, we haven't really seen all that much of it.
He is definitely still learning the game, both defensively and going forward, but to be fair he has been moved around a bit at Bath so he's only really had about half a season at 12.
His defense is good: a very good tackler although he gets caught out of position sometimes, but as I said, he's still learning the game let alone his current position.
I can see him becoming a very good distributing 12, he has the skills to put in great passes and the feet to keep defenders honest, all he needs to do now is improve his understanding of the code.
From some of the close up shots during matches you can see he is very competitive! Which could be an indicator of the right temperament for internationals.
Examples of his distribution:

If you look his tries (both codes) a lot come from him actually ducking under tacklers, which is something he can really use at 12.
I think he could end up playing at 12,13 or 15. Lancaster said a while ago that he saw him as a full back, although that was before he started playing at 12.
If he can show that his size isn't an issue when competing for the ball as a FB then I think he would be well suited to it, but it's a big if.
Gary Gold has said that he wouldn't rule out playing him at FH either, but I think that's less realistic.
TL: DR I think he's pretty decent.
