Back looks good. You took the boo to the glue line like a good Bowyer:) The belly side will need more wood removed to achieve the 40 pounds you want at 30 inches, I designed a lot of belly wood into that blank, so you could work "SLOWLY" into a bow:) Those pencil lines I scribed on the belly side of the Osage and down along the sides of the Osage, were just a starting guide for you. I am sure you will need to take the facets down more on the sides and in more towards the center of the belly, even more to get down to 40 pounds. Scribe more lines lower along the side and in more towards the center of the belly, use a compass, and keep them even. Look at them to make sure they are even, symmetrical so to speak, before you rasp again. Actually I would take the sides right down to the glue joint eventually, without rupturing the glue joint, just like you did the boo on the back! There is a lot of wood there, and that is what you need to approach this tillering process. You should end up with a sweet radiuses belly. Just be sure to sand after rasping to remove any deep rasp marks. When is doubt, STOP and ask questions, Grasshopper:)
