What a beautiful scene! The red color is a nice choice, and I'm glad you chose to put stars in too
Did you sharpen it a bit, cause i'm noticing there's a fine, light red line going around the tree. The other thing I thought of that would do that is when you take out whatever color was behind it so all you have is the tree. It tends to leave a strange line around the object afterwards. Anyway, I was just wondering if that was the case in this pic. If not, do you know an effective way of getting rid of it?
