2007到2010年间程亚杰创作了系列人像油画作品《仲夏》《望月怀远》《春华秋实》；《如诗岁月》《牡丹红》《细语》；《风华》《心锁》。程亚杰作品中的唯美主义一直是一个主题，孜孜以求，这些作品洋溢着东方之美，又散发出西方美学人本主义追求个性的气息，同时蕴含现代艺术的时尚感。程亚杰这组人物有情节情结，唯美的画面描绘了女子细腻的内心世界。
《望月怀远》低头浅笑，手上的动作暴露了心中的秘密；《春华秋实》目光热烈，大胆饱满，手扶椅背含着紧张的期盼，背景的“人”“物”暗喻主题；《仲夏》描绘了女子的侧背影，含蓄可人，略带羞涩，同样用背景“人物动作”把内心躁动渴盼表现出来，仲夏季节的热烈，怀春少女的心声在暗夜中蔓延。 
2007~2010，During this period, Cheng Yajie produced a series of portrait oil paintings including Midsummer, Looking at the Full Moon, Missing One Far Away, Spring Flower, Autumn Fruit, Time of the Poetry, Peony Red, Whispering, Elegance and Heart Lock. Aestheticism has always been one of the themes of his paintings which reveal the beauty of Orient, the individualism pursuit of humanism in the Western aesthetics as well as the fashion of modern art.
Looking at the Full Moon, Missing One Far Away portrays a beauty, with her head lowered and a hint of smile, whose hand motion exposes the secret of her heart. The plump beauty with warm eyes in the oil painting Spring Flower, Autumn Fruit puts her hand onto the back of the chair with a revelation of anticipation. The "person" and "objects" in the background imply the theme of this painting. Midsummer portrays the profile of the beauty who is slightly bashful with a significant smile. Her motion reveals the inner restlessness and anticipation, which implies the hotness of midsummer and voices the aspiration of the beauty.望月怀远春华秋实仲夏
