You're off to a good start, I certainly like what you're doing with the river.So this is a WIP base I am making in a hard and laggy modpack called Revolution 3.
It's nowhere near ready yet, but this is what I got so far.
Being not particularly good at building, any suggestions would be appreciated.
Also, BUMP. You're welcome.
The overall styling is quite nice- try mixing it up with a few different variants of the same block (bit of birch planking with the oak, one of the chiselled versions quarry stone to go with the plain)
The log support beams are a nice effect too.
The best advice I can give is be brave, practice, and experiment.
