looks good! Progressing really well for a first jet. A suggestion, the wing root fairing, or wingbox, is it not connected to the fuselage and in one mesh in this plane? because on the real airplane, the wingbox is smooth, not bumpy as it is in your rendering. If you take a look at the photo below, you can see that the wingbox has an up and down curve to it, starting from the third passenger window backwards. The blue and gray stripe provides a pretty good guide as to the shape of the wingbox
