Probably wrong but to me the balancing weight on those wheels looks a bit big compared to the mass of the centre lug, have you tried them for balance on an axle? Ian
Lots of things to take into consideration. as you have stated

There are plenty of plans out there it all depends on what you like from small stationary type engines, locos and even traction engines. something simple to start with as there are various kits out there where you can buy castings. It all depends on the equipment you have and any experience you have.
I may have picked a project that is a little more advanced for a total novice like myself as I am only just started in model engineering especially working with metals instead of wood which many of the models I have built in the pass.

Long after project completion they will have value, especially for someone attempting the project with more limited skills, equipment or time.
You can't get anymore limited experience than I have learning as I go but have done a lot of research before starting this journey.
I am lucky that I was able to buy the larger machines in one go but still buying the little nick naks that go along with it as and when needed.
And as for time I seem to have plenty of that with all the things I try to fit into a day
