It looks great!I believe you should have played some more with the shadows though. I thought it was some sort of flower, or an ore before reading the title.The medium you used has so much potential, so does the subject.Like I said, great work! But maybe concentrating on the definition of the shapes by taking advantage of the highlights, therefore emphasising the contrast between the leaves(?) within the artichokes will bring more to the eye.I love how this has sort-of a comic book style, too. I'll watch your gallery and I will be looking forward to seeing more!
