Top photo, his G-2 goes straight up from his ear tip as he is looking away and the other ear is back. Look at the width of the back of his head for scale. Middle photo, he is looking at a quartering towards angle of 30 degrees or so and his main beam sticks out past his ear making his spread look wider because of the angle. Most bucks racks "lean back" from their head as they look alertly towards the viewer and at a slightly sideways angle this would give the appearance of more width. Bedded photo, the bucks face is slightly away shortening the view perspective on his face but assuming he is 7 to 7 1/2 inches eye to nose, his G-2 is 16 inches or so and you can scale the rest of his rack of that.
OSOK is right in that 190 bucks look huge in velvet and there is no mistaking one if you have seen enough of them. A 190 buck takes 19 inch 2's and ATLeast 12 inch average fork depth if he doesn't have world class mass and a 25" plus inside spread. That buck doesn't have any of the criteria. If you were hoping for a 190 buck and you shot this deer, you would be sadly mistaken.
Of course that's just my opinion. I could be wrong.
Nice buck though.
