Welcome to the forum!
My first recommendation will be to use the image links from the gallery, so that the pictures appear in the thread, like this:
You'll get a lot better response if people can immediately see your work.
I also think you're being very hard on yourself, that's definitely better than "not even half-decent"; your golds are good and you've got some nice detail on the purity seal.
There's a couple of areas where it looks like the blue is a little thick, but it could just be that you've taken very close-up photos, which make everything look worse than it is! There's definitely a few mould lines on there, which can distract from the paint job, so you might want to spend a little more time on prep.
I think the main thing "wrong", for want of a better word, is that some of your edge highlights are a little scruffy, which messes up the lines of the model. Should be easy to fix, just go back over with the base colour and use it to neaten up the edges of the highlight. I'd also look at washes (or whatever the current
GW term is) to give more texture to some areas (e.g. The wax bit of the purity seal.
To be honest you're at a good starting point, so if you've only just restarted the hobby you probably just need a bit of practice. Hope that helps!
