They're perfect and they fit a niche that hasn't been fit yet. Male Miqo'te are small, sure, but on the bulkier side (Similar to Siberian cats, British shorthairs, Bengals, or Norwegian forest cats). Au Ra males are lean, but with a more hourglass shape with larger thigh muscles and broad shoulders. Lalafell have no s*xual dimorphism. Midlander males are thin, average, and have minimal dimorphism to the females. Highlanders are bulky, testosterone-chugger looking males with massive amounts of chunky muscle. Roegadyn males are barrel chested and have small hips in comparison to their bodies. And Hrothgars... are hrothgars.
From what we see in the video, male vieras are slim, possibly shorter than their female counterparts (which makes sense, bunnies irl are dimorphic with the females being larger than the males), and fit the niche of lean, smaller shoulders, and smaller thighs.
From this image, the male is on the left and the female on the right.
