The review on Konsten.net in connection with Wikström's exhibition at Galleri Gunnar Olsson in 2015 wrote the following (translated from swedish):
‘She is now holding a solo exhibition at Galleri Olsson with images inspired by a stay in France. From painting minimalist monochrome paintings on various materials, she has switched to digital images. The link between the physical paintings and the digital presentations seems to be the image ‘Blauwe Vitrage’ from 2012, a manipulated photo of a blue curtain that clearly refers to minimalist painting and abstract modernism. As well as having an interest in changing the expression and scale of value of a material by simple but decisive means. The digital image is presented in a thick glass with rounded corners, as physical in space as an oil painting on canvas or an object.

In the digital process, there is an interesting critique of painting and an approach to design. She asks, for example, how unique painting really is and where the boundaries of pretentiousness lie. You can also see that she is trying to push the boundaries of painting. What is a painting, what can be painted with, colour, memories, reflections, pixels, time, impressions?
[...]
The new paintings Kristina Wikström shows take another step away from the abstract towards the representational. She paints with memory as watercolour. Memories and visual impressions in transparent layers upon layers. It is nice to look at impressions with a transparent eye, to be open to another reflection, to refrain from stating the obvious or the probable. It is sympathetic to accept that everything is complex and can constantly present a new angle or bottom that can affect the overall picture. This non-hierarchical approach is a common denominator in all the images in the exhibition.’
