Sorry,, Didn`t get to finish that last post so just put the link !! Take your painting and hold it in good light at an angle so you can see across the surface !! If you see the broad strokes that do not match the scene on the painting,, it is likely a print !! I am not sure about yours because the pic does not show well !! But from what I could see it was indicative of a print !! In other words when you see the water,, the paint stroke should match it !! In other words if I paint a tree trunk,, the strokes will match that shape !! There can be different strokes behind it but not on top of it !! Hope this is understood !!
Many prints have the texture over the picture so if you run your hand across it,, that is what you feel,, just the texture !! Rarely does anyone match it to the painting itself !!
Another thing to check is the signature,, that is the last thing painted by the artist !! You should not see gloss on top of it !! It will be a dull,,not shiny signature !! Only exception to this is that if the painting was varnished which is rarely done !!
