Thank you Elizabeth for your compliments!
Regarding more squinting of eyes or not, I was smiling as big with my mouth closed. I actually look quite stupid when I smile like that. What I did was that I just stopped holding my lips together. What I think was did most harm on the paper was actually a black pencil that I used, it did the same thing to another painting I just finished (of a couple of houses).
Now I have to go!
