Excellent! A very ambitious picture in a number of different ways! The angled view of the stocks provides good visual interest... it would have been simpler, art-wise, to show a full-on setup (feet and stocks directly facing the viewer, no tricky perspective or body proportioning to keep straight), but the scene would be far less arresting! The surrounding grays in the color pallet bring the central purple motif into sharp relief, providing Sammi with fine focus. And the first-person point-of-view involves the spectator directly and intimately with the action (really feeding the tickling fantasy!) The gentle shadowing is quite effective: just enough for good modeling, not so much as to make the scene overly-dramatic and compromise the hilarity! More and more, Sammi is beginning to assume the look of an finely tuned animation character... I could easily see a series in her future!
