There are definitely a lot of options presented here (almost as if there were 36!), and there is a lot of them that are fairly inventive. With a selection like this, you can't really complain, as you can ignore the ones that you don't like. However, I feel like there may be a few too many options presented here that emulate class features. As an example, the wildshape one is a bit odd to me, and gives players options that the Druid doesn't even have until later levels (turning into flying creatures). Some of the crafting feats also, if I'm not wrong (which I very well could be) are unnecessary, as a player can already craft those items during downtime without the need of a feat.
There is a great number of options that seem to be well underpowered for a feat, or don't provide much to a player. Those ones almost seem like the old style of feats which would follow the normal progression for gaining feats, and not the way that 5e does it. I personally dislike feats in 5e having prerequisites for other feats, but maybe that's just me.
