Looks really nice. On the suggestion for sewing, I agree, when we do these with the Boy Scouts (I must've helped cut and sew two dozen at least) we always have them sew it on the inside mainly because the bushes will do a number on stitches and exposed blanket edges. If you can, I suggest sewing a trim along the hood, sleeve ends, and the lapel all the way around the bottom to the other end- basically anywhere there is exposed blanked edges. The blanket stitch used at modern rendezvous is nice but ineffective and incorrect. Just use a solid colored bias tape and have at it! But I can understand if you want to wait for a while, it still looks great as is!
