Fairly hard PBN with great detail
The owl really stands out when it is complete and the feathers looks amazing. If you are looking for a challenging PBN, then this is it! There is actually so much detail that is so small that many of the spots that do not have numbers in them are not for number 1 white. Because of that I would recommend doing white last and double check on the key that it is really a white spot. Some spots will be obvious that they are not supposed to be white but rather a different color that doesn't have room for the number in it. Also, I would advise doing the black and #11 gray in the beginning. It becomes hard to tell the colors that are shaded vs what was painted gray. I used a 10/0 brush for the smaller detail but overall I really liked the brush that was supplied with it (I don't usually).
