Great look. I'll add a couple of quick observations. I have a full cap "rock star" wig with I-lace island, and I can tell you that is scary how realistic the scalp look is with I-lace. Keep in mind that you can go with just 1/2" -3/4" of lace in front, if you use blond hair there it won't be a lot to dye.

While this wig did not have blond, I have used blonde and dyed it. IMO, when there is 1/4" or so of blonde hair at the root it can look more realistic. There is an illusion of "baby hairs" growing, and the darker hair just appearing "from nowhere" as it were. Not that it would stand up to micro-close examination, it's more of a subtle subliminal thing that will appear as natural to the average observer.
