in my opinion yes.
though I have to say ur rendering and colours continue to improve.
for these views I prefer shadows that are cast behind the object and offset to the side a bit as imo thats optimal lighting angle to describe forms.
in ur mockup the shadow seems to defy the lightsource.
its also ok to be painterly and smooth out the shapes of shadows such as under the roof rather than being pixel for pixel from what is being cast.
with windows u can try reducing the highlight brightness and making it just a single pixel line at the bottom as if we're seeing where the edge of the glass meets the frame.
u can also perhaps keep in mind to reduce ur reliance on lines when ur drawing.
umm cant think how to say it right now but for example the solid vertical lines in roof are just too obvious and...liney for me.
sometimes its nice to suggest shapes rather than litterally having a line, which means when u do make solid 1 pixel lines, they carry more weight.
hard to say much else off my phone but good luck with it.
