Exactly, I have had no reason to buy a new DSLR, although the lens I like best cost more than a new body would, this is the one I use mainly
Just won a G7x II on ebay for £405, almost new, less than 200 pictures took with it, with a small tripod and SD card, if I don't like it, I'll get my money back easily enough
As for your photos they are great, you shouldn't doubt yourself, and as long as you like them, then thats all that matters anyway, as you take them for you to see don't you

I have some photos that are nowhere close to what an expert would call great, but I love them just because of what they captured rather than any quality or anything
