王渊幼习丹青，赵孟頫多指教之，故所画皆师古人，无一笔院体。陶宗仪于《辍耕录》卷七中记其“幼时获侍赵魏公故多指教。所以傅色特妙。天历中，画集庆龙翔寺两庑壁”，可见其艺术活跃于元代中后期。夏文彦《图绘宝鉴》评其“所画皆师古人，无一笔院体”，其画山水师郭熙，花鸟画师承后蜀黄筌，先勾勒后皴染水墨，浓淡深浅，极有韵致，得写生之妙，时称“绝艺”。人物师唐人吴道子，一一精妙，注重线条勾勒，不讲究墨彩渲染，史称“有笔而无墨”，自成风韵。尤精绘花鸟和水墨竹石，当代绝艺。天机溢发，肖古而不泥古。

表现手法属“黄家富贵”体。唯舍色彩而取水墨，通过勾勒和水墨晕染区别浓淡向背，造型极精严，神态亦颇生动，作到“墨具五色”的艺术效果。同钱选一样，王渊在花鸟画创作上起到了承前启后的作用。类似王渊画风者还有边鲁、赵衷等人。广为后人师法，弟子有臧良等。
       另据陶宗仪《辍耕录》记载，天历中王奉命画集庆龙翔寺门首壁大鬼，高三丈余，遵刘总管之嘱，“先配定尺寸，画为裸体，然后加以衣冠。”若水依法 为之，果善。说明王渊对于人体解剖有所研究。

王渊的传世作品主要是立轴，画于至正三年（1343）的《花竹禽鸟图轴》（现藏在山西省博物馆）、至正四年的《竹石集禽图轴》（现藏上海博物馆）、《桃竹锦鸡图轴》（现藏北京故宫博物院）、以及《秋山行旅图轴》等四轴现藏在台北故宫博物院，手卷以《牡丹图卷》为佳，现藏北京故宫博物院。
       故宫绘画馆藏有其至正九年（1349年）作《山桃锦鸡图》，笔墨极文雅，乾笔皴擦，淡墨渲染。工整而精确地画出花竹禽鸟，以水墨渲染，明净秀雅，自成一格。这种墨花墨禽的表现形式在北宋时即已出现，但王渊的类似白描画法的花鸟画却更鲜明地表现了文人的审美情致，被视为其创新。
       其作品还有《花竹集禽图》、《秋景鹑雀图》、《良常草堂图》等，今存有《花竹禽雀图》、《花竹春禽图》、《花竹锦鸡图》。三幅画均为纸本，立轴，墨笔画，创作年代分别为 1344年、1346 年、1349 年。
