All I can comment on your beard is that it looks good (at least from the picture in your avatar) and as far as your progress I think you will do fine but you will likely find that you're going to have to pretty much just wait for it all to happen.  Yes, biotin is good for your hair growth but I don't think it will make it grow any faster (may but I don't know that for sure.)  Another thing that I hope you know and that is that blond facial hair growers have it a bit harder than darker haired facial hair growers in that the blond hair is not as visible as darker hair, but when developed looks really sharp. I'm making a guess that with a good three months of growth you may like what you have (even more than what you have now.)
