I think the length of the coat does look more accurate for the 40s on you.
If you do not have as broad of shoulders as your model the shoulder pads should stick out further off the edges of your shoulders. None the less because of the padded boxy cut this really does not show.
The sleeves still do not look full length on you. To me at that point they look like they appear to be in between 3/4 length and bracelet length.
The difference between 3/4 length and bracelet length is a good few inches, is significant to me, and is significant to my coat customers. Some want the shorter 3/4 length sleeve to show off their gloves, some wear gloves only up to their wrist or just bracelets/watches only wanting their arms to show up to that point preferring bracelet length, and then there are others who want to show as little of their arm as possible but will accept a bracelet length sleeve because they really like the coat. Those who really prefer a full length sleeve might settle for a bracelet length but would not settle for a 3/4 length sleeve because it was just too short.
In 1937 a study was done by the US Department of Agriculture(USDA) studying the size of US people. The most common height of US women was said to be 5'3" tall. In 2011 another study was conducted by the USDA who said the most common height of US women was 5'4" tall.
Even though this study provided the most common measurements Americans still varied in size too much to make a one size fits most.
In 1940 the pattern maker Dubarry made their standard clothing patterns to fit women who were 5'3" to 5'6". Even after seamstresses still had to make allowances when making clothing from patterns for people within those heights because no two people were alike in every area.
Being no two people are alike fit should not be determined based on how a garment fits someone else. By your example you can see the sleeve of your coat hits one point of your arm but it might hit a different point of someone else's arm who is the same height as you depending on their individual measurements.
When considering buying a coat a wearer should to allow 2 to 4" extra in each area to allow room for clothing underneath and ease of movement. Shoulder seam to shoulder seam when there are defined shoulder seams, shoulder seam to cuff or in some cases when there are shoulder pads or the sleeves connect at the collar; underarm to cuff, armpit to armpit, bust closed, waist and hips when fitted, sweep, and length from nape of neck to hem are important all together to determinine proper fit.
