Hello, Young Man ! You are getting the idea now .Point .The upper walkway around the boilers .Why don't you take some .020 sheet plastic or heavy card to make those walkways .That way they'll look more in scale .
See , As a modeler you need to look at the parts with a critical eye and especially the boxtops .Those pictures will aid you a lot . Not the sides , but the picture on the front . That walkway should not be that thick in scale .
You'll have some trouble with the front stairs and the corner rails too , but we will get to that soon enough .The wood in the stack looks great . Now you are catching on . The texturing , weathering and woodgraining are par-excellance !
This is an excercise in co-operation , teaching and building .You will look and say "But , wait , I'm doing what T.B. said , not what I wanted to do ". If you do that it's your choice . I firmly think you have an exacting nature and you want this to be a fine model .That's what I am here for . Enjoy and , believe me , You will learn a lot to put with the skills you are already showing . Good on you Mate ! T.B. P.S. I am enjoying the daylights in being able to help you !
