Hello Kenny, and welcome to the forums - glad you could join us.
Those are lovely photos - thanks for sharing them.
Regarding your possible switch to Pentax... I shoot more than one system, but Pentax is my favourite by far. It has it's quirks and limitations, just like any other system. For me, a major benefit of shooting Pentax is these forums. It makes a huge difference to me and many others to have such an active user community, both socially and as a source of learning, help and advice.
The K-1 is proving to be an outstanding camera - again, not without its quirks, but overall a highly capable pro-quality camera. I have no reason to suspect you'd be anything other than delighted with it
