Portuguese to English Art/Literary Art, Arts & Crafts, Painting Ceramic tiles

Taken from an exhibition on the history of Portuguese ceramic tiles or azulejo. Here's the full sentence:

"É uma pintura cerâmica de qualidade pelo exercício cuidado das aguadas e das várias tonalidades de azul e pela representação equilibrada da anatomia, obra provável de um artista com formação na pintura de cavalete."

I could hazard a guess at many different translations in this context, but if anyone has come across this term before, your input would be much appreciated. And if you need any more context, feel free to ask in the discussion section.

Thanks!
