Looks good.
I would get rid of the light blue box-shadow and blue border for .form-control:focus (definitely inherited from bootstrap css)
.form-control:focus {
border-color: #66afe9;
box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(102, 175, 233, 0.6);
outline: 0 none;
}
...or changed these colors to the more appropriate shades of red, say
.form-control:focus {
border-color: #900;
box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(172, 0, 0, 0.6);
outline: 0 none;
}
or something like that.
