The ceiling is the limit

Após mais um par de horas a olhar para a parede e a sacudir latas, este mural iniciado há já algum tempo, ficou assim. Se bem que, com franqueza, perguntamo-nos se não seriam necessários mais alguns retoques...

Would you say this wall is finished? Again, we were there today. We painted for a couple of hours more, but sincerely we're not sure the job is completely done... Any suggestions?
