hey im new to photoshop and tried doing some black and white colorization. Heres my second attempt at this, first time Ive actually tried to blend in some colors rather than a single gradient for the face etc. What do you guys think? where did I go wrong? (other than that patch of hair on her shoulder - I learned today to take care of problems of form before coloring them in: shes made of a face and a seperate layer of hair from a different version of the photograph)
