Nice job, this piece has taken major steps forward! A few things that may help would be to adjust your values so you establish a hierarchy of importance and more depth in your composition. A lot of your elements are fighting for center stage. The flowers are beautiful, but they're pulling a lot of attention away from your main portrait subject, and the birds are almost entirely lost among the leaves. By pushing certain elements back with shadow, and pulling others forward with light you can direct attention to the areas you want your viewer to focus on. I'd also consider cropping out the vine leaving frame top left, and the sun/moon/star elements in your borders. These elements further pull the eye out of the central focus of the image rather than keep the eye moving inside of your composition towards your subject. I like how you have the petals breaking this border, it helps lead the viewers eyes into the composition rather than pushing them out, so you could possibly continue that motif across the top of frame. Hope this helps, keep up the good work!

Hi! If you're referring to extreme perspective/foreshortening, it's still the same concept, just with the vanishing points closer together on the horizon line. There's a Proko video that touches on this for a more visual example: https://youtu.be/LIuNehjFmUU An exercise you could do to build up this skill is to practice drawing boxes from a variety of vanishing points, including close together vanishing points, so you can start to get a feeling for how this affects perspective. Plus, once you're able to control extreme perspective on boxes, you can use this to place more complex forms like people/arms/legs into the 3D space. If you want a resource to turn to, I would recommend Framed Perspective by Marcos Mateu-Mestre as he gets into all the technical details of controlling your vanishing points.

You use your "mastery" of 1, 2, and 3 point perspective to create a box and draw your figure inside.
