My dreads seem loose is this ok or bad?

So I just had got my hair done like 3 days ago and the chick who came over to my house and did my hair, backcombed it and then twisted it using dread gel etc... It seemed pretty legit, but now it's just that they don't seem to be as tight as some other peoples dreads according to what a friend had told me and told me I had to get it redone. But he used a different technique... and he has more Caucasian hair and I have really curly hair. So now more to the point! Do they seem loose because I'm using a different technique and they need to go through the locking process. Or the chick who did my hair did it wrong and I need to get them redone?
