Nice job..I really like those "shark tail" Forts, and the Academy kit is quite nice.
Just a couple of accuracy critiques: your model has the B-17B "blister" style gun emplacements for the waist, belly, and radio room guns. B-17Cs and D had the flush waist windows and radio hatch, and the "bathtub" belly gun (and I believe most Bs that survived long enough had them retrofitted.) I believe all the correct bits are included in the kit, so if you feel like it they shouldn't be too much trouble to switch out. Also, the vents on the upper wings are not exhausts, they're hot air vents for the turbosuperchargers..nothing comes out of them but clean air, which actually deflects oil and grime from the engines around the vents.
I hope I'm not being too critical..at least you finished yours. I've been working on an RAF B-17C off and on for over ten years and still have finished it!
