Madewithrobots-No tracing,no grid.I plot a few points on major structures when I scale up for reference just to keep me on track.With the time involved I dont want to risk messing up on the placement/spacing of major structures and I need to keep the erasing to a minimum,cant hurt the paper.
Mrs Hat-Never tried painting,I always liked graphite/black and white.I never found out till years latter that there are professional graphite artist,that do amazing things with pencils.Seeing the things they were able to do really got me on it.
