Personally I'd call that traditional. It's not as much white space as you can see in a modern quilt, and it's certainly no more than I've seen in many old-fashioned quilts. There's a long tradition of red and white quilts, often with a fair amount of white visible. Put "red white quilt" into Google Image and you'll see what I mean. Obviously this isn't just red and white, but it does seem to fit into that tradition more than any others.
Lovely quilt, by the way. Are you sure you don't want to do curves? Those generous white areas would be lovely for showing off some nice curvy quilting designs in red thread. Are you hand or machine quilting?
