One Great Year

i finished my 5th piece last week, its pretty good i like it. and now i am on my 6th, it will be done today for sure. (when i am done with the 6th piece i will post them on here together) my next piece i have an idea for but the last one is going to be a happy one. i've been doing them all in pencil but the last one is like a new beginning. its going to be of my step dad and my new family, it represents like starting over and moving on, so i was wondering if i should do that one in color? or stay with the black and white.. because i dont want them to look like they dont go together if i did it in color. sooo any advice mama bbbb??
