"Bij het bekijken van het schilderwerk van Iris Frederix wordt de toeschouwer direct bevangen door vreugde, opwinding en ontroering. De schijnbaar moeiteloos gepenseelde werken van deze kunstenaar blijven hangen, behagen, vragen oproepen en ontroeren. Haast on-Nederlands met een onmiskenbaar internationale allure. Werken als ' Kleine Prins' of 'Ora et Labora' , wat een schoonheid. Verzamelaars van het betere figuratieve schilderwerk kunnen watertanden. De musea met figuratieve kunst moeten zo snel mogelijk plekken aan de wand leeg maken voor schilderijen van deze getalenteerde kunstenaar."

"The work of Iris is of a high quality. Her subjects differ, from portrait commissions to wonderful memories of her travels around the world. Her style is realistic, but with an impressionist touch, colorful, warm and intense. Always a pleasure to look at."

"My wife and I are very pleased with a portrait painted by Iris. This portrait is a reminder of our wedding and we wanted to capture this event in an image which would reflect who we are. With this idea we went to Iris who helped us with determining the basic composition. Prior to the start of the painting, Iris had us posing in various positions in front of a camera. The photo’s gave us a good insight into the final composition and translation of the theme which Iris had in mind. Both my wife and I had separate posing sessions during the detailing of the painting. Because of this we could follow the realisation step by step. Although we saw the preliminary work, the end result was thrilling and we received it with much excitement."

"I have purchased a very intemate painting from Iris, a buddhist monk standing next to a Bodhi tree. I was very lucky to be able to purchase the painting because in the pre-exibition phase the whole series was almost sold out. Lucky in the sense that I would have bought them all. Since then I have sold my entire art collection, but I kept this one. Because of its sheer beauty, the attention which Iris has put in the various details."

"In de salon van Hiddinks Amsterdamse woning springt op de wand met schilderijen een dubbelportret eruit van twee oude mensen, die elkaar liefdevol vasthouden. Het zijn Gerrit en Jo Hiddink, zijn onlangs overleden ouders. “Het schilderij is gemaakt door een jonge talentvolle kunstenares, Iris Frederix. .... Mijn moeder is twee jaar terug overleden en mijn vader vorig jaar. Het schilderij is een mooie herinnering aan mijn ouders. De kunstenares heeft hun ziel geraakt.”

"Amazing! When I saw the portrait of our son for the first time after Iris finished it, I was absolutely moved. I never thought a painting could do that. We are so very happy with the personal touch Iris has put in the painting she made of Max. You can see that the painting is filled with the personality and soul of Max. The painting feels alive and Iris has captivated his character perfectly. We are so proud with this beautiful portrait. Thank you Iris!”
