First step was to take individual pictures of star and blooms. In Adobe Photoshop Elements, an inexpensive program, I then did some selecting and copying to isolate the parts of each photo necessary. Each was repeatedly pasted onto a "new" page and the star changed in color. Sizing and aligning everything was a breeze, as was filling the background to unify the end result. With text added, my project was done. Really. It's simple, but success does take practice and familiarity with the options available. But hey, there's nothing to lose - not even a sheet of paper.
Go play. That's my best advice. Photoshop is one of my favorite toys. :-)
