BlueJaye, it's great that you've jumped in with both feet. The thing about makeup is that we all need to practice a lot. I've learned everything I know from reading and observing videos on the internet. There are thousands of amazing tutorials. There will be fails, but the more you practice the better you'll get at applying it. You'll be amazed at how much of a difference hiding the beard stubble and shadow can be. I shave extra close, and then conceal the blue shadow before I put on my foundation and other makeup.
I wish you all the best, and no doubt you'll have great success since you are willing to practice.
Hugs,
Sally
