I'm not an expert at painting but my friends have given me a lot of tips
I have no problem with sharing some info. Although, there is some information I can't pass on (I promised to keep it a secret).
Yep, I water down the paint a lot. It makes the finished product look smooth but since it's watered down, you have to paint a loottt more layers. Hmm, I'm not sure what else to say about painting.
I remember your blind bag Fluttershy. I love the hair! Good luck with future figures
