should've shot?

[kt]

hey guys tell me what you think. monday night found me up a tree about 15 yds from where i should have been. eventually i lucked out and had a deer come out where i needed her to (its a doe only season) so either way she walks she is gonna get some. well i draw back and at about ten yds she needs to take one more step. instead she turns head on and starts walking right at me still about 10 yds. she looks around and at full draw my shot would have been straight down right under the white throat spot and hopefully into the vitals. the spot i was in is thick stuff i was afraid of a limited blood trail so i let her get away. should i sent her a muzzy?
