I think the most important and sometimes hardest thing to learn with this art form is, less is more! If you overpaint, you cant fix it wheras if you underpaint, you can always add more. Yes you can strip the kit but its a pain. Go slow and stand back and really take in your work as a whole as you go. I used to stare up close as I painted and not realize I had overdid it. I had many blue overdone babies! I like to take pics and look at those as I go. It gives me a new perspective snd pics up mistakes that the eyes can miss. Your first few babies wont be perfect probably. This is a difficily art form to master but a really fun one! And it is very addicting lol.
I havent painted in over a week and im going nuts. I think im having withdrawals lol.
Also, do not use the warm blush by BB by itself. You will have an oompa loompa baby. If you want to warm up the skin tones, try some burnt umber or maybe an ochre wash very thin. You can use warm blush if you mix it with lots of flesh or another color. Hope that helps and isnt too much Info at once. Sorry, I love reborning andove talking.about it lol
Good luck and feel free to ask for help as you go. Welcome
