Though my forte lies primarily in realistic paintings and old master copies, I'm extremely experienced and adaptable with acrylics, which will suit your large abstract artwork project to a tee. Having honed these techniques over the years will allow me to deliver your desired Helen Frankenthaler-esque style with all its nuanced complexities.
My adaptability as an artist doesn't end in mediums; it seeps into styles too. My understanding of colors, compositions, and balance – developed through countless portraits and landscape works – runs deep. So much so that even though abstract art might be different from what I typically do, I guarantee a meticulous adherence to the proportion and harmony of the warm-cool color balance you'd like to see.
Lastly, while I acknowledge not having many examples of abstract work in my portfolio per se, this only serves to amplify our potential collaboration – as you get to guide and benefit from my wider skill set, delivering something distinctly ours rather than just another imitation.
