I've ridden English nearly my whole life as well and I love meeting other riders, first timers or veterans. Any advice I might have is...
Heels down, toes up. A lot of people tell you to put your heels down, but they never really explain the purpose of this. So here's a personal feeling. When I canter, I sink all my weight down to my heels. I feel a lot more in control and balanced when I do this. It just FEELS natural.
Also, where you're looking is where you're going. You want to tend to look where you're going before you go there. This also goes for the ground. Try to keep your eyes off the ground...for obvious reasons. XD
Also, think of your arms as an extension or your reins. Bend at the elbow, but keep a relaxed hold and shoulder.
You look like a natural. And like all great things(post withdrawn by author, riding just takes practice and time. No one is truly an expert and I've always considered myself far from such, even with the amount of time I've been riding.
