I definitely had enough yarn leftover to make this long-sleeved, but I chose not to.
Modified the bottom of the sweater and sleeves with ribbing. The garter stitch edge was really unflattering on me. Anyhoo, for the sleeve ribbing I went down two needle sizes to size US 8 (5mm) to make it fit more snugly around my arms without having to decrease stitches. Worked like a charm.
