Marko Jezernik je svoja likovna dela prvič javno predstavil pred šestnajstimi leti, pred tem pa je nekaj let risal in slikal "zase". Od tedaj je imel vec kot trideset samostojnih in dve skupinski razstavi.: v Šentjurju, Celju, Ljubljani, Vidmu, Beogradu, Radovljici, Rogaški Slatini, Reki, Radencih, Portorožu, Kamniku in v Bruslju ( 1992 ).

Kot piše Drago Medved, se je Marko Jezernik ves čas ukvarjal z akvarelom, vzporedno pa je gojil tudi risbo in grafiko. Akvarel je kot tehnika in način likovnega razmišljanja najbližji avtorjevemu značaju; zvedavo zazrt v svet, lirično občutljiv in trdno povdarjen tam, kjer mora biti.

Njegove kompozicije so preproste; zgornja in spodnja polovica lista sta ločeni z imaginarno črto odseva, ki izvira iz motivike same - jezera, gladine, obzorja. Iz narave črpa tisto skrivnost, ki mu daje moč tudi za licenco poetico, za samostojne sprehode v iskanje neznanega, skrivnostnega.

Tej želji sledijo tudi barve s ponekod drzno povdarjeno rumeno - kot sprostilnim momentom. Prevladujejo hladne barve, zlasti modra in zastrto zelena ter mnogimi odtenki sive.

Jezernikovo slikarstvo je impresionisticen zapis njegovega odnosa do sveta, ki ga doživlja zanosno, a hkrati razumsko. Tudi zato po Medvedovem mnenju še dolgo ne bo zapustil akvarela, morda nikoli!

Sixteen years ago, after several years of drawing and painting only for himself, Marko Jezernik finally showed his art to public.

Since then he has had more then thirty one-man and two group exhibitions:

in Sentjur, Celje, Ljubljana, Videm, Belgrade, Radovljica, Rogaska Slatina, Rijeka, Radenci, Portoroz, Kamnik, Bruxelles.

Acording to Drago Medved, Marko Jezernik's primary interest throughout this time has been aquarelle, although he continued to draw. He has also produced some graphic works. After sixteen years of creativity, aquarelle stands out as the artist's prefered technique. As a technique and a method of fine-art contemplation it corresponds most closely to the artist's character traits, that is, his child-like curiosity, lyrical sensitivity and firm emphasis in just the right places.

His compositions are simple; an imaginary line of reflection separates the upper from the lower part of the print and is introducedby the motif itself: a lake, its surface, the horizon...The artist taps from nature a harmoniy which also endows him with poetic licence, and permits independent excursions into unknown and the mysterious.

This tendency is seconded by his use of colours. In his compositions the yellow bursts forward in a moment of relaxation amidst the predominantly cold colours, especially blue and subdued green, and the many shades of grey.

Jezernik's paintings are an impresionistic recordingof his world view, which is passionate and rational at the same time. For this reason, according to the critic Drago Medved, aquarelle is likely to remain Jezernik's favourite technique for quite some time, perhaps forever!
