Hi, Aszule.
I congratulate you on your intention to make a quilt for your friend. Good luck!
I like the fabric you have chosen. I also like the pattern you are considering. But as the other posters have said, that is a rather ambitious project for a first go. The part "Peckish" noted, about the sewing of bias edges being finicky, is very true. One thing you might consider, to achieve a similar effect but with a much easier task, is to make a "four-patch stack and whack." The edges on this are all straight-grain, and so they are easier to sew, there are fewer pieces for each block, and the effect is similar to the pattern you are considering.
Here are some links for info about the four-patch version:

Note that a lot of the pix on the links above add "fancy" finishing touches, like sashing or setting the blocks on point, but you don't have to do that to have a beautiful and impressive quilt.
Good luck!
