Fair enough.
With these images, you need to keep in mind that the miniatures are like 5cm in size (that's 2 inches for my Ameribros) and that small mold lines are exaggerated in these large photos.
Overall, the miniatures, armor plates and panels that are protruding from other surfaces have nice sharp edges - they aren't GW-sharp, but they are not as blunt as they look on most photos or in videos.

You can see some mold lines, especially on the front of the missile-covers, but they are easy to get to, the only really bad one is on the right hand, gotta work careful when removing that.
In the left image, there's something on the left foot that looks like a very bad molding jet spot thingy (the hell are they called?), but it's actually just a spec of plastic that clung to the figure. You can see it's gone in the other image).

Nice panels/armor plates. I especially like the connectors between the upper legs and the hip. The arms have nice details that'll catch washes and highlight the shape very well, so do the legs and the rest of the body.

The screw-head-shaped thingies are about a milimetre in size, so that's a really tiny detail and it's still crisp and clear.

Aside from being one sexy beast, there's a lot of fine lines and details all over this mech.
I think, the edges are best seen in these two images: they are slightly rounded, but not much.
They are sharp enough for nice highlighting.
