cool shots all of em
i enjoy creating screen shots myself
my only suggestion is to get rid of the edge pixelation
i use the blur tool
the programs i use are photophilter its free
faststone image viewer also free(this is a good program for saving different sizes for Avatars and such)
i try to make my screen shots look like photos. so they should have some blur to em the pixelation really killz the photo look so that's mostly what i concentrate on.
keep at it
