Azzza, I loved this the moment I read it. I do have a some suggestions to make (you're not going off that easily) but first let me say the nice part?
I like how you reversed this. you did not start it by the person, you, viewing the painting which, to me, is named ''Euphoria'' and thinking about it. but rather with what you think or your impression/description of it, as if you're too deep into the masterpiece in front of you to think otherwise, so you got it right in the middle of your head and then you let us out. you explained. so to me it was not only reversed but also every line uncovered another detail, until in the end we got the whole picture/idea.
so again, I loved the idea and the way you penned it but my problem was the wording/ word choice. I think you could have worked better on it to be honest and you are able to do so. you were a bit impatient it seems with this. let me explain for example..
''Canvas splashed with vibrant colors,
where red and blue amalgamate
causing lilac hues to drip...
an art work of a master painter.''
Canvas (cloaked?) with vibrant colors
where red and blue (wed?)
and lilac hues drip
I do understand that tastes vary and this maybe a bit feminine for you XD or maybe you're comfortable with your word choice. which does not take away from the uniqueness of the piece but you could make the piece even more unique if you worked more on the words? in my opinion at least? oh well.
I very much enjoyed it though, Azzza, so thank you. I even enjoyed ruffling your feathers a bit. you're so peaceful for me to pick on you elsewhere.
