In addition, your two paintings (Zhang Yijun's are also paintings) are not complete, so you can't tell whether they are entertainment works or family masterpieces. It's even harder to evaluate.
According to my experience in collecting calligraphy and painting, Liu Kui's landscape painting should be able to reach every square 500 yuan, which has appreciation potential.
Zhang Yijun's grape paintings are quite famous, and they should be able to sell around 200 yuan per square foot.
Liu Kui, a native of Ningyang, Shandong Province, is a contemporary young painter and graduated from the Academy of Fine Arts of Shandong Normal University with a master's degree. Study landscape flowers and birds. His works were selected in the 11th National Art Exhibition in 2009, and the Shandong Exhibition won the Excellence Award, and the 8th China Gongbi Painting Exhibition was 20 1 1. One foot has stepped into the China-US Association. Try harder, and you can become a member of China Artists Association by attending an exhibition. His works have been selected into some domestic art exhibitions for many times, which has great collection potential and appreciation potential. Take good care of it and you will be happy in the future.
The next painting is by Zhang Yijun, a member of Shandong Artists Association, Shandong Calligraphy Association, painter of Qilu Painting Academy and president of Jinan Judas Painting Academy. Good at painting flowers and birds, good at painting grapes. His work won the silver prize in the National Youth Cup Calligraphy and Painting Competition. Painting has the potential of appreciation.
