Ted I am no expert and maybe there was nothing that could have been done about it but while the "whites" as in the dresses are have nice detail in them the blacks seem to be lacking detail a bit.
It may of course have been that the black material was genuinely so black that even texture and the usual folds, turns etc were not visible anyway. The dullness of the day wouldn't have helped.
Only you will know this.
Overall they all look pretty good . I especially like the one where the lad is peeping around the groom's legs and the little bridesmaid has what appears to be a dummy in her mouth. Kids can often make the pictures at weddings. This one will brings laughs when the album is brought out for years to come.
