I would let it sit for a day or two and then make a decision. I know that we are our own worst critics, and you are falling right into that pattern....see, you are a true quilter already.
I prefer SID when I quilt. Everything else seems to cover up my pattern. Sometimes I do a diagonal thing....maybe it is called a cross stitch. I stretch blue painter's tape from one corner to another and follow that line as I sew. That may be something you want to try? I bought a SID foot that really helps me with the SID. It follows the seam exactly. Might be worth looking into?
At any rate, let it sit a bit. I think it will look better than you think.
