Welcome aboard the
Congrats on picking up the t21. As petegnj stated, you won't regret buying it.
Now all you have to do (not really HAVE to technically) is show off your new photos by posting some on here when you get the chance.
You can just show them off or if you desire, you can ask or comments and critique to help you take better shots in the future.
Again, welcome aboard and hope to see your work soon!
