Thanks @castonia XD for the 3 point perspective that was from the cuberush artschool, but for the shapes and value studies i just started by going to google, typing in geometric shapes renders and taking an image and copying it as much as i could while trying to figure out how its rendered with light, its a bit tough at first but after a couple of tries you get used to it and it gets alot more fun and easier. So just draw a small 2 point perspective and draw boxes, then from there you can go to the other geometric shapes and add and subtract to those shapes :). ill see if i can find anything online for free and let u know XD
