张善孖笔下猛虎，既不失虎的威猛，又富有人性，含有一种温情，同时结构准确，华南虎的特征明显。张善孖笔下的虎，林语堂曾赞:“凡一肌一脊、一肩一爪，无不精力磅礴，精纯逼真。”诗人杨云史写诗称赞他虎作:“画虎先从养虎看，张髯意态托毫端;点睛掷笔纸飞去，月黑风高草木寒。”
此图中猛虎漫步于山崖岩石和树木草丛之间，神色凝重而又庄严不可侵犯。浑身黑黄相间的花纹，胸腹部和四肢内侧有几片白色毛斑，那厚厚的黑黄相间的毛似件大绵袍，平平整整地披在肩上。四肢粗壮，行动间体态呈流线型，肌肉结实健美，充满了无穷的力感。爪尖刺出趾外，尾巴粗长，带有黑白相间的环纹，如同一把钢鞭一般微曲摇摆，白嘴巴上还长着长须，张着血盆大口，显示出气吞山河之势，整体威武雄壮，其须挺直利索，其唇色泽润洁，最有神的当属它那双吊睛大眼，虽是威严虎目，却也不乏光华神韵，折着月色望去，只觉着两颗璀璨明珠耀人双眼，当真是虎目含威情却步、月影迷蒙现光华……的确是百兽之王。下笔处处是经典，墨色浓淡均匀，猛虎神情栩栩如生，显示出画家高超精湛的画工和舍我其谁的英雄气概！
“自从兽类饶人性，堪笑人间有兽行”一句，写出了张善孖对于虎的热爱。张善孖一生中，最喜画虎，也最擅画虎，可见一斑。
此《猛虎雄霸山川图》正面是一隻斑斕猛虎，自左上方向右下方行走而下，蓄势待发，沉著自信，氣勢威嚴，必勝之勢，震撼世界，大聲怒吼，象征通告世界：中華民族同仇敵愾，浴血抗戰！体现出磅礴的浩然正气和英雄气概！
Zhang Shanmai's portrayal of the fierce tiger not only embodies the majesty of the tiger, but also exudes a sense of warmth and a precise structure, highlighting the distinct characteristics of the South China tiger. The tiger portrayed by Zhang Shanmai was praised by Lin Yutang, who once said, "Every muscle, spine, shoulder, and paw has boundless energy, pure and realistic." Poet Yang Yunshi praised his tiger works in a poem: "When painting a tiger, first look at raising the tiger, Zhang's beard carries the slightest hint of emotion; when finishing, throw a pen and paper away, the moon is black, the wind is high, and the grass and trees are cold."
In this picture, the fierce tiger strolls between the cliffs, rocks, trees, and grass, with a solemn and solemn expression that is inviolable. The body is adorned with black and yellow patterns, and there are several white hair spots on the chest, abdomen, and inner limbs. The thick black and yellow fur is like a large cotton robe, draped evenly over the shoulders. Thick limbs, streamlined posture during movement, muscular and muscular, full of infinite power. The claws protrude from the outside of the toes, the tail is thick and long, with black and white ring patterns, swaying slightly like a steel whip. The white mouth also has long whiskers, with a big mouth open, showing the momentum of swallowing mountains and rivers. The overall majesty is majestic, with straight and sharp whiskers, and its lips are smooth and clean. The most divine is its pair of hanging eyes. Although it is a majestic tiger eye, it also has a dazzling charm. Looking at it in the moonlight, only two brilliant pearls shine in people's eyes. It is truly a tiger eye with majestic emotions but hesitant, and the moon shadow is hazy and shining... Indeed... The King of Beasts. The strokes are classic everywhere, with even shades of ink and lifelike tiger expressions, showcasing the painter's superb craftsmanship and heroic spirit of sacrificing oneself for others!
The phrase "Since animals have shown mercy towards human nature, it is worth laughing at the existence of animal behavior in the world" expresses Zhang Shanmai's love for tigers. Throughout his life, Zhang Shanmai was the most fond and skilled at drawing tigers, which is evident.
On the front of this "Tiger Dominates Mountains and Rivers" is a colorful tiger, walking down from the top left to the bottom right, ready to take off. It is confident, majestic, and victorious, shaking the world with a loud roar, symbolizing the world: the Chinese nation is united against the enemy, fighting with blood! Reflect the majestic righteousness and heroic spirit!
