I'd keep shooting and hold off a little. Framing is expensive and you'll probably do better than these soon and then spend more money hanging the new ones instead. Some general c&c on these -
1. interesting subject and well exposed, but better if the crossed leaves weren't centered. DOF a little bit of a problem too - if everything but the stuff in the center were oof, it could be OK, but you have some stuff in the corners that is also sharp and a little distracting.
2. pretty good bird shot, but looks like you focused on the feet, not the eyes, and the twig in front of the bird's neck really detracts.
3. this is the best one. You left room in front of a moving subject, which is always good, but maybe a little too much in this one. Part of the dog looks underexposed - perhaps you could bring that out if the detail is there in the original exposure.
