Don't panic, the shed has started, mine started after about ten days and it sucks, but is part of the process.. Those lovely grafts are going to be gone soon and you'll go through the long wait until regrowth starts, in about 3 months or so. Stick it out. Try some witch hazel and aloe vera gel on the redness. To be honest, it doesn't look too bad at all. You're going to spend the next few months constantly looking in the mirror...:D
Looking back, my hair looked far worse, just after the shed, than it did pre op.
