Photoshop -- cut and paste

The Photoshop class I'm taking is great!  It is really interesting, and I'm being taught much more than I can remember  . . . but in time and with practice, I'm sure it will all come into place.  Here are some pictures from making the first project-- it is for cutting and pasting (from files the teacher provided) -- The butterfly was made first, and then reduced in size so more things could fit in.
