This is all to much speculation on how and what is in the composition - it is a bunch of "poo Poo" to chatter on about full frame and cropped when the user is not one bit interested in what gets cropped out of a full frame when they get what they want from a cropped.
When one has their camera set for large photos it is darn easy to take a step or two back to get "your full frame" shot.

As 'd3200prime' mentioned on his/her post, he/she want a prime for portrait, 50mm on a DX camera will be like a 75mm, it's good for shoulder to head shot of portrait. it's okay too for full length shot, but with group picture, you are right the 35mm is the one for group and scenery, he/she already has a 18-70mm, it's a very good lens for general use for scenery.
