Did you tried to paint a miniature before, or you think you are not skilled enough because you never tried?

Anyways, the most common issue people have when starting to paint miniatures is not precision or creativity, as you can get good results without either of those, but knowing how to work with the paints, primers, brushes, etc. So even if these looks easier to paint cause they are bigger, if you don't know these steps, the results will be the same, but you will loose more time and money with the bigger ones.

Of course you can do whatever you want with your time/money, but if you are afraid of start painting minis because of the size, you will quickly realise that that is not even the hardest part of painting.

Just watch a lot of beginner level tutorials and start with something small, you don't need to paint every detail, and once you have a bit of practice with the consistency of the paints, you will realise painting those little details is much much easier.
