I think it’s Participial phrase
because participial phrases have past tense or present words, and in this question it has the word “had” and “hoped” and those are both past tense.
Sorry if I am wrong but i think it just seems like that’s what it could be.
Jade should add details such as the drawing name and his own name EITHER IN THE BOTTOM LEFT OR BOTTOM RIGHT OF THE DRAWING.
The details should not be too close to the edge of the drawing because the drawing is probably still going to be framed. This location is the best to add the details because that is the place most collectors check first.
