If you want to make a queen sized quilt as your first quilt, go for it. The first one I ever made was a queen sized bedspread and I was about 13. I hand quilted it.

As long as you are an experienced enough sewer and can keep your seam allowances consistent, then the size of your quilt top doesn't matter. A queen sized quilt will cost you right around $200.00 at MSQC if you have them quilt it. I don't machine quilt large quilts because I don't have the room around my machine to do it.

I'd watch most of the tutorials that Jenny has done to get an idea of what pattern to make. The one that JimsQueenie suggested would look good in the Dogwood fabrics.
