First print the photo on a piece of graph paper instead of copy paper. Rule the paper into nine pieces, cut them out. and copy each one separately another 300%, and if it is not big enough, do it again.
When it is the size you want, tape all the pieces together into one big sheet,. This is your guide - don't cut it up.
Trace off each different color area, separately, and remember to ADD seam allowances, use that tracing as a pattern, pin it onto a piece of fabric, and cut it out. Embellish with thread painting details if you want. or later.
Sew two pieces together, then add more around them.
As you progress, lay the work you have done on or near the guide, you might want to embellish some more across the sewn together pieces.
