I think both sound good HWA, although I think there's a grammar slip in the first:
"The lucky kids to get you as their fantastic teacher."
Maybe you meant "The kids are lucky to..."?
Just remember when you send it- NO EXPECTATIONS!!! It may get no response at all and you've got to be OK with that. Send it expecting no response, do it because it's what YOU want to do. Then if it does get a response, cool. If it doesn't, no biggie.
