Thanks Steven. I always have the hardest time at this stage, trying to block in, doing the tonal, and landmark everything. It is a real juggling act. I always find several things wrong when I come back at it.
First I thought of doing the glasses later but I find it hard because my glasses keep on shifting. I said if I commit to it I will not have to worry about it. But I think you are right. I should leave it to the later stage.
Next step is to correct proportional and tonal differences. Wish me luck.
