my planning:
i have an idea....a mental picture...make a list of thinks ill need, kit, foliage, etc
i make a birds eye view sketch of the dio, when i get the wood i draw it on, work on the kit, work on the ground, foliage, paint and so on.
im compulsive about making my dios and models look great....so, as an artist (paint paintings too......guess what they are of??....( i made a big A-10, another A-10 with a P40, a Stutka diving, aircraft carrier Enterprise......and many more to come.. hehehe)) i make A LOT OF SKETCHES! do research, EVERYTHING! but the best picture is the one in your MIND! enjoi- DJ
