Cute Pup!! Great exposure on the first two the third one is a tad darker than I would like. but you have great composition and really captured Sly! Good work!
Cute dog...
I agree with the last comment, it is a tad bit dark.
The last one looked like it could have been a cool "running toward the camera" action shot.
I think those are pretty nice shot esp if you are new to photography. It is better than a lot of mine without using photoshop to fix stuff. I recommend you learn photoshop because it will lt you add special effects to your photos and also to correct minor errors in exposure and so on, but of course a good pic doesn't need much photoshop.
