I think this is great. I love the texture.

The only thing I suggest is to compare the length of the cliff's shadow with the shadow of, say, a building. I think the cliff shadow is too short.

Maybe that's a perspective thing. Most of the map is overhead, but the cliff is not. I'd say that if the cliff were narrower and the entrances were at a sharper angle, it would match even better.

These are just comments, as I think the map is really good.

Oh dear. Wow. The "Direct Download" from Humble Bundle is markedly different from the ProFantasy web site. I never used the HB direct links, so I didn't see what you saw. I very strongly suggest that you copy your HB keys and paste them into your Registration -> Downloads page, and then download the installers from there. I'm not sure if they just renamed the installers or if anything else changed. I personally wouldn't trust a download from anywhere but ProFantasy.

The ProFantasy route also has the benefit of always being there if you forget your keys, lose the installer, lose the SM PDF, or want an update.

How to make the mountains pop? I'm not sure they need to change. I kinda like it. Maybe a shadow of some kind, but I don't think it's needed.

I like it!

I have two suggestions. I agree with what JulianDracos wrote, by the way.

Don't get a 4K display. I love them for everything except CC3. Scaling CC3 for 4K doesn't seem to work for me. A 1080 HD display is perfect for CC3, in my opinion.

Get SSD for storage. I think it's hard to find a model without SSD. It's important enough to mention, though.
