if you like your trackplan, and it is working for you, then you have gotten the hard part out of the way. a layout with bad track gets boring pretty quick.
if you are going to use this one as a practice layout, then i suggest you make your buildings, and labor intensive scenery (trees, bridges, etc.) removeable or at least salvageable. you are going to be mighty proud of some of your work and may want to carry it over to your newer and better layout.
as the volume of your good stuff grows, larger and more complicated layouts become easier because a lot of the high quality work has already been done.
from what i see, you’re off to a fine start. keep going and keep building. as your experience grows, so will the quality of your work. do not stifle yourself at this stage of construction, keep moving forward.
