作品風格上，受到了插畫家索爾·斯坦伯(Saul Steimber), 托米·昂格勒(Tomi Ungerer ), 伊西德羅·費雷爾(Isidro Ferrer)和頭藝術家尚-米榭·巴斯奇亞( Basquiat)或凱斯·哈林(Keith Haring)的影響，創作風格呈現一種非常自由的藝術表現形式，就像孩子們創作時一樣。
大頭主題既可以作為圖畫敘事的平台，也可以是隱述他敘事的實際發想和思想來源。莫伊喜歡呈現有趣的小故事，例如展示畫作主角沉浸在自己的思想和環境中的稀奇生活，因為他認為外在的形象是可見的，但人內心的想法是不可見的，因此他將人內心真實的想法透過作品呈現，題材主要探討人與人之間的關係，與在人生不同階段中的過程，作品中經常出現梯子、階梯和鋼索等元素，就像是人和人之間在關係中需要跨過的差異與距離。
由於其特有的敘事語言習慣，他的作品顯現了許多不同的風格，時而顯得十分精緻，時而有力、批判卻又有趣，但無論如何其作品總是充滿詩意、優雅和動感。
Spanish artist Moisés Yagües' style is simple, clear, fresh, and harmonious. His works predominantly feature round-headed characters, and within the large heads, various objects such as ladders, flowers, and steel cables are hidden, as if exploring the ever-changing inner world of individuals. Upon closer inspection, embroidery can also be discovered in his works. In terms of artistic style, Moisés is influenced by illustrators such as Saul Steinberg, Tomi Ungerer, Isidro Ferrer, and artists like Jean-Michel Basquiat and Keith Haring. His creative style presents a very free form of artistic expression, reminiscent of the way children create.
The theme of large heads serves as a platform for pictorial narratives and also conceals the actual ideas and inspirations behind his storytelling. Moisés Yagües enjoys presenting interesting little stories, showcasing characters immersed in their own thoughts and environments, as he believes external images are visible, but the inner thoughts of individuals are not. Therefore, he uses his artwork to reveal the true thoughts within people, primarily exploring relationships between individuals and the processes in different stages of life. Elements such as ladders, stairs, and steel cables often appear in his works, symbolizing the differences and distances that need to be overcome in relationships between people.
Due to his unique narrative language, his works display various styles, sometimes appearing delicate and at other times powerful, critical yet entertaining. Nevertheless, his works are always filled with poetic, elegant, and dynamic qualities.
