First etch. I'd say it turned out so-so.
I'd say that's pretty damn good for a first go man, don't be too hard on yourself!
Looks to me like you could've done with a longer etch time if possible to get it a bit deeper, that would help with the sanding stage and using a flat block as the top layer of paint would be more easily removed.
Also I'd definitely recommend a couple of light coats of paint then waiting for it to cure overnight, if you sand too soon it lifts much more easily when sanding.
Finally, if you find the paint has dulled after sanding a couple of layers of clear coat will bring it right back and also improve the contrast.
Give it a go next time and see if that helps at all, as I say for a first etch what you've got there is really good!
Cheers,
