Erm, it hasn't been finished yet? :)
For a start, your loops which go through the rows and columns: you don't
have the correct number of columns. You've got 10 columns in the code.
Look at your diagram. How many columns are there?
Doing a nested for loop will work ok for what you're trying to do.
For now, concentrate on just getting a picture full of * (i.e. 25 across).
Then when that is working, work on making the stars *not* be printed in
the correct places, such that you have the three stripes appearing.
