Homemade Mayo

I've altered this recipe a tad while preparing it, I will post the recipe I used, and will add my alterations in green. The end product was very good, however I still find it quite runny and a tad too much mustard. I plan on trying it again with a little bit less mustard, although I would like to know if anyone else has suggestions for me to try to make it creamier and less runny.
